• Added capability to analyze and design pedestrian/bicycle only bridges including optional maintenance vehicle loading. The capabilities are consistent with the recommendations of NCHRP Project 20-07, Task 244.
• Bridges with mixed girder types can now be modeled. The general girder family (I-Beam, Voided Slab, etc) must be the same for the entire bridge; however the girder type (WF74G, Type I, Type II, etc) can be mixed in the bridge model. This feature works very well for modeling box beam and slab bridges where different beam sections are used to accommodate a given roadway width. It is also effective for modeling bridge widening projects.
• Bridges with a different number of girders and different girder spacing in each span can be modeled. Girder spacing can now be defined uniquely at each end of a span. This feature enables the modeling of bridges with flared/splayed girders.

• When computing prestress loss due to slab shrinkage, the deck area is based on the gross slab depth rather than the structural slab depth. Shrinkage occurs before the sacrificial depth is worn off. The sacrificial concrete shrinks and contributes to the loss.
• When changing the height of a girder in the girder library entry, the position of the strands measured from the top of the girder did not maintain their position relative to the top of the girder. This issue has been resolved.
• For beams controlled by ultimate moment capacity, the longitudinal reinforcement for shear check would fail even thought there is adequate reinforcement to resist the maximum moment at the section. This issue has been resolved.

• A file named Trucks.pgs that contains definition for AASHTO H and HS trucks as well as CalTrans P trucks is provided with the software. These trucks can be easily imported into a PGSuper project using the library import feature.

• Camber in debonded beams was computed incorrectly. The moment due to the eccentric prestressing at the ends of the beam were based on all of the strands being bonded.
• The Bridge Site Stages (1, 2, and 3) have been given more descriptive names. Bridge Site Stage 1 is now Deck and Diaphragm Placement Stage. Bridge Site Stage 2 is now Superimposed Dead Load stage. Bridge Site 3 is Final with Live Load Stage.
• Girder dead load moments were incorrectly based on a continuous span analysis when girders are made continuous prior to deck placement. A Girder Placement analysis stage has been added to correct this problem.

• Under some conditions, section properties in multi-span bridges were computed incorrectly. This problem has been corrected.
• Girder stresses during lifting were computed incorrectly if inclined lift cables were used. This problem has been fixed.
• For the lifting stability calculations the offset factor, F_o, was applied to the midspan deflection relative to the lift points. The offset factor should be applied to the total deflected shape of the member (i.e. girder end to midspan). This problem has been corrected.
• An overlay was drawn in the Bridge Section View even when an overlay was not defined in the bridge model. This was only a display problem and did not affect the structural analysis or design. This problem has been corrected.

• PGSuper would crash when the "Edit User-Defined Loads" view is opened. This problem has been fixed.

• For structures that achieve continuity before deck placement and are analyzed as Simple Spans made Continuous the wrong slab, diaphragm, User DC, and User DW moments were used when computing prestress losses. Simple span moments were used even though the girders were continuous at the time the load was applied. This problem has been corrected.
• The composite area for girders with composite decks was reported incorrectly. This problem has been corrected.
• The "WSDOT Summary Report" was reporting the stress demand at the harping points incorrectly. This problem has been corrected.
• The program settings for the Master Library and Workgroup Templates was always reverting to the "Download and synchronize..." setting regardless of the option chosen. This problem has been corrected.
• Fixed problem computing stresses at temporary strand removal stage. Dead load stresses are those due to the girder only. Prestresses losses are those at the time of shipping plus the effect of temporary strand removal.
• The K_id parameter for shrinkage losses between transfer and deck placement was using the wrong location of the centroid of the prestress force. This problem has been corrected.
• The weight of a future overlay was incorrectly added to the superimposed dead load moment for purposes of computing losses from deck placement to final. This problem has been corrected.
• Improved validation of Overlay input

• The bursting zone checks for LRFD 5.10.10.1 were incorrectly based on the total jacking force. LRFD 5.10.10.1 prescribes the force to be 4% of the prestress force at transfer. At transfer is defined in LRFD 5.2 as the prestress force immediately after transfer. The bursting zone checks have been updated to use the correct force level.
• A TxDOT Double T section has been added
• Prestressing strands were being included in the negative moment capacity calculations. Since strands do not extend across a pier, they are not present in the section resisting the maximum negative moment. As such, the strands should not be included in the analysis of this section. For consistency with this and traditional engineering practice, prestressing strands are ignored in all negative moment capacity calculations.
• On some systems, PGSuper is unable to update registry settings. This would cause PGSuper to become unstable and crash. This problem has been corrected.

• Negative moment capacity was not computed correctly at all sections near an intermediate pier. PGSuper was not considering the layout of deck reinforcement when determining if a girder was symmetric about its centerline. Capacities are computed at one point and mirror across the centerline for symmetric girders. This problem has been corrected.
• The wrong capacity reduction factor for negative moments was used. This problem has been corrected.
• The value of E, in the WSDOT Girder Schedule Report, is now computed at mid-span. This eliminates the effect of debonding (typically used in voided slabs) on the location of the resultant prestressing force in the straight strands.
• The required area of shear reinforcement can now be computed by creating a Details Report. The required Av/S is reported in a table labeled Required Shear Reinforcement in the Shear Capacity Details chapter of the Details Report.
• Fixed display of debonded strands in the Girder Section View.
• PGSuper would crash if the Girder End Distance was longer than the Bearing Offset (See the Connections Library). The End Distance must be less than or equal to the Bearing Offset. PGSuper has been updated to enforce this requirement.
• PGSuper would crash if the girder spacing was too narrow. This problem has been corrected.
• Due to internal rounding, input values would change slightly. For example, an input of 2.5" might change to 2.4999999". Changes have been made to reduce the number of times this input rounding would occur.
• The Prestress Force and Strand Stress table has been added to the TxDOT Summary Report
• PGSuper project files could not be opened if the Comment field in the Project Settings dialog exceeded 256 characters. This problem has been corrected.
• The vertical component of prestress is now considered at the harp points. In previous versions Vp at the harp points was taken to be zero.
• Some of the stress checks given in the Summary Report were erroneous. Some checks were reported as Pass when they should have been Fail and visa versa. This was only a problem with the Summary Report and it has been corrected.
• Allowable compression limits where not properly checked for inclined girders, without impact, during hauling. This problem has been corrected.
• When computing live load distribution factors for Type h, i, and j sections using the lever rule, the edge of slab offset rather than the curb line offset was used. This problem has been corrected.
• The degree of continuity at all piers with must be determined in order to build the correct structural analysis models (See LRFD 5.14.1.4.5). The determination of degree of continuity is now reported in a more clear and concise manner.
• When computing the live load distribution factor for shear, if I or J for type f and g cross sections exceeded the range of applicability limits given by the AASHTO LRFD Bridge Design Specifications, PGSuper would report an error. LRFD 4.6.2.2.3a states that the distribution factor for moment may be used in this case. PGSuper has been changed to use the moment distribution factor instead of reporting an error.
• Updated TxDOT templates and libraries
• Added Slabs to the AASHTO templates and libraries

• PGSuper can now model multiple spans. Analysis can be performed for simple spans, simple spans made continuous, and the envelope of these two.
• Added support for provisions of the AASHTO LRFD Bridge Design Specification, 4th Edition, 2007. Note that the inequality given in Equation 5.4.2.3.2-2 is taken to be >= 0.0 even though it was changed to 1.0. This change is an editorial error in the 4th Edition specification.
• PGSuper can now perform a fabrication optimization analysis (See the PGSuper Theoretical Manual for details).
• Governing design parameters have been added to the design outcome report.
• Added a weight property to the traffic barrier library entry. The linear weight of a barrier can now be input to override the computed value.
• In the Bridge Section View, a grayish-green color is used for future overlays to make them appear visually different then overlays applied during the original construction.
• Shear stresses at the girder/slab interface can now be computed by either the LRFD approximate equations or by the classical shear flow equation, VQ/Ib.

• Spread box beam bridges can now be analyzed and designed.
• Deflections due to the removal of temporary strands were not being computed properly in the camber analysis. This problem has been corrected.
• When computing loads for intermediate diaphragms, the effect of skew on the diaphragm length was not taken into account. This problem has been corrected.
• The magnitude of intermediate diaphragm loads on exterior girders was computed incorrectly. This problem has been corrected.
• The skew correction factor for shear for Type F sections (voided slabs and box beams with composite deck) was computed incorrectly. This problem has been corrected.
• The average stress in prestressing strands was not computed correctly in the moment capacity analysis. The initial strain fpe/Eps was not added to the strain due to flexure at ultimate. This problem has been corrected.
• The harping point location was incorrectly report in the Input Summary chapter of the Summary Report. This problem has been corrected.
• The specification check stress for Service IA was failing to correctly identify over-stress values. This problem has been corrected.
• Miscellaneous performance enhancements were made to speed up the automated design algorithm.
• Fixed several memory leaks.

• The Master Library and Project Templates are now published on the Internet. PGSuper will periodically check the PGSuper catalog server for updates and download them as needed.
• Libraries and Templates for TxDOT bridges are published on the PGSuper catalog server.
• Libraries and Templates for standard AASHTO girders are publised on the PGSuper catalog server.
• Several optimizations have been made resulting in shorter analysis times.
• The mild longitudinal reinforcement defined in the Girder Library is now considered to be seed values. Longitudinal reinforcement is independently defined for each girder. The input data can be quickly reverted to the library seed values.
• Diaphragms cast into a girder (such as end walls on U-beams) can now be modeled.
• New methods for describing strand grids and inputting the number of strands has been implemented. See the PGSuper documentation for details.
• WSDOT has rescinded its deviation from LRFD 5.8.3.5 (Longitudinal Reinforcement for Shear). These computations have been removed from PGSuper.
• The modulus of elasticity can now be directly input or computed based on concrete parameters.
• When computing elastic shortening and elastic gain, the centroid of the prestressing force is taken to be at the centroid of the permanent strands. This provides a consistent location for computing the concrete stress at the level of the prestressing over the life of the girder.
• Overlays can now be treated as future loads. When used as a future load the self weight does not factor into loss calculations and the loading is applied in Bridge Site Stage 3 instead of Stage 2.
• The graphical user interface is more interactive. In the Bridge Model View, elements of the structure can be selected and manipulated. Pop-up information is now available by hovering the mouse over beams.
• Added the capability to specify normal values for the concrete parameters and post warnings to the status center if these threshold values are exceeded.
• The image files used in the various reports are cluttering the main application folder. Image files have been moved to a sub-folder called "Images"
• Intermedate diaphragms can be modeled as interior or exterior. Interior diaphragms are placed between webs inside the girder and exterior diaphragms go between the exterior webs of adjacent girders. Interior diaphragms may be cast when the girder is constructed or at the bridge site during deck construction. Diaphragm layout rules are now associated with individual girder types.
• If the girder end size is longer than the prestress transfer length, the point of prestress transfer was included in the bridge model. This problem has been fixed.
• Fixed bug reporting status of Optional Live Load Deflection Check
• Fixed erroneous error reported if equal min and max values were input for width of variable-width beam sections.
• The slab offset can now be computed so that slab geometry and girder deflections match the roadway profile or matches the camber at time of slab casting. Matching camber at the time of slab casting is necessary to avoid construction problems in girders with large cambers and large superimposed dead load deflections.
• The flexural design algorithm has been improved
• Specification checking and/or automated design for: strand slope, hold down force, slab offset ("A" Dimension), girder lifting and girder hauling have been made optional.
• Strand slope for specification check is now computed as the maximum slope for all harped strands. This was previously the average strand slope.
• The degree of strand bond due to transfer, development and debonding is now taken into consideration when computing the area and C.G. of prestressing.
• The effective flange width may now optionally be taken to be the tributary slab width.
• Load modifiers where not included in the load cominations. This problem has been fixed.
• Fixed compatibility problems with Internet Explorer 7
• You can now define your own load factors for the Strength I, Service I, Service IA, and Service III limit states.
• The application of diaphragm loads setting in the Connection Library entry was not saved properly. This problem has been corrected.
• Symmetrical vertical curves can now be described by inputting the full curve length in the L1 field and leaving the L2 field blank.
• The effect of long term losses from transfer to deck placement were omited from the creep loss calculation for losses from deck placement to final (See LRFD 5.9..4.3b). This problem has been corrected.
• The concrete strengths required to pass the various Service Limit State stress checks is now reported.

• Fixed bug reporting stress check status in the Casting Yard and Bridge Site Stages 1 and 2.

• The profile effect of the slab offset was computed incorrectly when the bridge had skewed piers. This problem as been corrected.
• The weight of the traffic barrier load was reported as weight per foot per rail and not weight per foot per girder. The problem was only related to the reporting of the load and not the structural analysis. The correct traffic barrier load was used in the analysis. This problem has been corrected.
• Intermediate diaphragm loads were computed based on the diaphragm cross section and girder spacing. The width of the girder is now deducted from the spacing when computing the diaphragm load.
• When computing the cracking moment, Mcr, the dead load moment on the noncomposite section, Mdnc, did not include user defined loads applied in Bridge Site Stage 1. This problem has been corrected.
• Harping points can now be located from the center of the girder and can be limited to a maximum distance from the reference point.
• Girder concrete properties are no longer reset to default values when the girder type is changed.
• For connection library entries, the bearing offset and girder end distance can now be measured normal to the pier/abutment or along the centerline of the girder.
• The coefficient for computing modulus of rupture is now a user defined value. Agencies can set the value of the coefficient in the Project Criteria library.
• The girder end distance, defined in a Connection library entry, is no longer restricted to be less than the bearing offset distance.
• PGSuper would permit the number of debonded straight strands to exceed the total number of straight strands. The program would crash with this input scenario. The problem has been corrected by limiting the total number of straight strands to be no less than the number of debonded straight strands.
• If strands were debonded over the entire length of a girder, PGSuper would crash. This problem has been corrected.
• The girder spacing input was inadvertently enabled for adjacent box beams. The spacing should be fixed at the width of the box. This problem has been corrected.

• Chamfers have been added to the Box Beam, TXDOT U-Beam, and I-Beam sections
• The section modulus for top of slab is reported in terms of equivalent girder concrete. This has been changed to be in terms of slab concrete. The value is more useful in this form.
• For girders with a cast in place deck and without temporary strands, the diaphragm deflection was deducted from both "C" and "D". This resulted in the excess camber being off by the amount of the diaphragm camber. This problem has been corrected.
• The bursting force was computed as 0.04(Jacking Force in Straight + Harped)/(Area Straight). This is incorrect. The bursting force is now computed correctly as 4% of the total jacking force less the force in debonded strands
• Changed the hauling details report to make the calculation of the mild reinforcement requirement for the alternative tensile stress limit more clear
• Each time a harped strand offset was specified at the end of the girder or the harping point, PGSuper would add the current input value to the previous input value. This resulted in the harped strands being in the wrong location. This problem has been corrected.
• For agencies using only one set of creep parameters, PGSuper would not let you enter the minimum and maximum values to be the same. This problem has been corrected.
• The picture for the TxDOT U-Beam did not show the dimension "D6". This problem has been corrected.
• Fixed problems reporting the parameter "TO" on TxDOT IBNS reports and the Export TxDOT CAD Data function.
• When PGSuper computed the maximum allowable jacking force for strand input it was including the initial relaxation losses. This loss was removed from the LRFD specification in 2005 and PGSuper was not taking this into account. This problem has been corrected. To have PGSuper update the maximum allowable jacking force to the correct value, open the girder editing dialog and step through all the pages. There is no need to change any values. Simply open the dialog, go through the steps, and press the Finish button, PGSuper will do the rest.
• The development length reduction between the point of initial bond and the full development point of a strand were computed incorrectly. A single linear interpolation was used and should have been a bilinear interpolation per LRFD 5.11.4.2. This has been corrected.
• For horizontal interface shear checks, both the requirements for Equation 5.8.4.1-1 and 5.8.4.1-4 were evaluated. The LRFD specifications say that only one of these two need to be satisfied. This problem has been corrected.
• Under certain input conditions, PGSuper would crash when multiple horizontal and/or vertical curves were used. This problem has been corrected.
• The girder deflection reported for camber differs from that reported elsewhere in PGSuper. The reason for this is that the girder deflection for camber is based on Eci and the other deflections are based on Ec. A footnote has been added to the Camber table and the theoretical manual has been updated to clarify this.

• Updated PGSuper for AASHTO LRFD 2006 Interim Provisions
• Fixed problem with false errors listed in the summary section of the Spec Check Report
• Fixed problem displaying harped strand locations in the girder cross section.
• Added new summary report for TxDOT users
• The Specification Check Summary Report does not list all of the failures and reports Bridge Site 3, Service III failure when it actually passes. This problem has been corrected.
• Mild reinforcement is now included, at an engineer's option, into the capacity analysis for flexure and longitudinal resistance to shear induced tension forces.
• PGSuper can now model complex roadway alignments including multiple horizontal curves, with or without entry and exit spirals, multiple non-symmetric vertical curves, and super elevation transitions. Loading and slab haunch ("A" Dimension) calculations have been updated to account for these geometric effects.

• The torsional constant, J, for voided slabs was computed incorrectly. This has been corrected.
• The effect of temporary prestressing was included in the stresses caused by prestressing in Bridge Site Stage 1. This problem has been corrected.
• For bridges with wide girder spacing, the effective flange width may have been computed incorrectly. This problem has been corrected.
• The entire bridge can now be offset from the roadway alignment survey line.
• Slab overhangs can now be specified for both the left and right edges.

• Added Stresses chapter to Details Report. This chapter lists the stresses caused by the various loading conditions
• Significantly enhanced plotting by adding plots of allowable stresses, stress demands, stresses caused by the various loadings, ultimate moment capacity and ultimate shear capacity. Several sets of analysis results can be combined into a single plot.
• Incorrect parameters were used when computing the longitudinal shear requirements at the face of support. Vu, Vs, Vp and theta should be those values at the critical section. See C5.8.3.5 for details.
• PGSuper can now model bridges made of a single girder line when the girder has multiple webs.
• Approximate time dependent losses were always computed for non-composite beams, even if refined time dependent losses were specified. This problem has been corrected.
• Added missing information to Specification Check Summary
• Transverse reinforcement (stirrups) can now be excluded from the horizontal interface shear resistance.
• Added details of modulus of elasticity of concrete calculations
• Added detailed of development and transfer length calculatinos
• Added prestressed slabs (voided and solid) and prestressed box beams
• Added support for debonded straight strands

• Girder lengths were not computed correctly when the skews at either end of the span differed. This problem has been resolved.
• The slab fillet dimension is now set to 0 when a composite overlay is used with adjacent girders (such as deck bulb tees).
• The weight of end diaphragms was computed incorrectly for skewed piers. The length of the pier along the skew was not accounted for. This problem has been corrected.
• The schematic picture for composite overlay decks was not shown in the details report. This problem has been corrected.
• The slab overhang dimension becomes inconsistent with the girder spacing when a composite overlay deck is used. For a composite overlay deck, the slab overhang should be exactly half the girder spacing. PGSuper has been updated to keep the slab overhang dimension consistent with the girder spacing.
• The width of composite overlay decks was computed incorrectly when piers are skewed. This problem has been corrected.

• Under certain circumstances, PGSuper would crash if the CG of the prestress force was shown on in Elevation pane of the Girder View window. This problem has been resolved.
• PGSuper would crash if you clicked on the Bridge Site 2 tab of a Design Criteria library entry. This problem has been fixed.
• For shear designs done by the modified compression field theory, in accordance with AASHTO LRFD 2005, the average shear stress was computed incorrectly. The shear capacity computations have been corrected.
• For noncomposite girder sections, such as the decked buld tee, the weight of the intermediate diaphramgs was not used in the analysis of interior girders. This issue has been corrected.
• The WSDOT method for computing shear capacity was not consistent with WSDOT BDM 5.2.4F.2. The calculations have been correct.
• The allowable live load deflection for LRFD 2.5.2.6.2 was reported as a positive value. However, the computed live load deflection is downward and reported as a negative value. For consistancy, the allowable live load deflection is now reported as a negative value.

• PGSuper would crash when a Spec Check Report was created. This issue has been resolved.
• PGSuper would crash when loading files on some versions of Windows XP. This issue has been resolved.

• The tension stress check in Bridge Site Stage 2 was unnecessary and it has been eliminated.
• Tensile stresses were checked in Bridge Site Stage 3 at both the top and bottom of the girder. The tensile stress limit only applies to the precompressed tensile zone (bottom of the girder). This has been resolved.
• The resultant eccentricity of the straight and harped prestressing strands, after temporary strands are removed, was computed incorrectly. This issue has been resolved.
• The slope of the harp strands was computed incorrectly when strand offsets were used. This issue has been resolved.
• Prestress losses for non-composite Deck Bulb Tee girders was incorrect. This problem has been resolved.
• Under certain conditions, PGSuper would applied a user defined load to the structure twice. This issue has been resolved.

• Added support for AASHTO LRFD 2005 Interim provisions
• Added tensile stress checks for temporary conditions (at release, lifting, and shipping) when tensile reinforcement is provided. Also computes the minimum amount of tensile reinforcement required to use the higher allowable stress limits
• Added support for noncomposite sections including deck bulb tees, double tees and ribbed girders
• Added support for TXDOT U-Beam section
• Added feature to export TXDOT CAD data
• Fixed problems with zero-length connections
• Fixed problems computing moment capacities with lightly reinforced sections
• Fixed problems checking longitudinal reinforcement for shear

• Fixed problem computing truck roll stiffness

• Temporary top strands and harped strands at the ends of the girder are now measured from the top centerline of the girder. These strand groups will retain their relative position to the top of the girder when the girder height is changed.
• When defining pier orientation by bearing, the bearing may be either left or right of the alignment
• Corrected the fill sequence numbering in the girder library entry section views
• Minimum and maximun time frames can be specified for construction. Cambers for the different timings is computed.
• Improved computation of "D" dimension
• Temporary strands can be used for shipping only

• Fixed problem with users inserting and deleting rows from the girder dimension input grid in the Girder Library
• Girder length, along grade, has been updated to account for roadway profile effects
• Complementary girder end skew angles were being reported in the girder schedule report. This bug has been fixed
• Removed WSDOT logo from main window and report title pages
• Corrected equations shown in Details report for U-beam distribution factors for shear on interior beams. The computations are correct, however the exponent on the first term was 0.6 instead of 0.8
• Corrected calculation of live load distribution factor by lever rule for 2+ loaded lanes for U-beam sections
• Added a Status Center feature as a centralize means of reporting and correcting errors.
• Girder bearing offset for pier 1 was used at pier 2 when computing girder lengths. This problem as been fixed.
• Added variable capacity reduction factor method as a WSDOT alternative to computing capacity of over-reinforced sections per LRFD C5.7.3.3.1. See "Flexural Strength of Reinforced and Prestressed Concrete T-Beams" by Seguirant, Brice, and Khaleghi for details.
• Corrected the dimensions for a W42G girder
• The available prestress force near the ends of girders are reduced along the development length to account for under developed strands at ultimate moment capacity
• Added support for LRFD 3rd Edition, 2004
• A step function for truck roll stiffness has been added for hauling stability analysis
• Added user defined concentrated and distributed loads

• Updated Bridge Geometry Report to include deck elevation, top of girder, and haunch depth over each web at 10th points along the girder. This information is useful in determining "A" dimensions for girders that are not erected plumb.
• Added optional live load deflection checks per LRFD 3.6.1.3.1
• Added a feature to import library entries from PGSuper projects to the PGSuper Master Library file. This feature is implemented in the LibraryEditor program and is only available to PGSuper adminstrators.
• The limiting moment capacity of over reinforced sections, per LRFD C5.7.3.3.1, is now reported along with the nominal moment capacity.
• Concrete properties are now directly input by the user. The concrete library remains so that common properties can be stored and recalled with a simple name. You can now directly input f'c and f'ci for each girder.

• The method of computing ultimate moment capacity has been changed to a non-linear strain compatibility analysis. Research to be published in the PCI Journal (2004) by Seguirant, Brice, Khaleghi has shown the PCI BDM Average Beta1 method to be unreliable.
• Added new WSDOT WF sections
• PGSuper would crash when loading files containing comments more than 255 characters long. This problem has been corrected.

• When ignoring range of applicability for distribution factor calculations, PGSuper would still evaluate curvature restrictions. Curvature restrictions are now ignored if the other range of applicability requirements are ignored.
• Updated TxDOT IBNS report

• Updated TxDOT IBNS report

• Harping point locations can now be defined by a fractional distance or an absolute distance
• The name of your project file is now given in the report heading.
• The input for environmental conditions, Exposure and Relative Humidity, has been moved to the Bridge Description dialog. This input was somewhat "hidden" in the PGSuper interface and designers were often overlooking these parameters.
• The last line of the TxDOT Summary Report lists the ultimate moment demand, but the label on the report says the minimum ultimate moment capacity. The reported value has been changed to the actual minimum moment capacity
• The weight of the girder slab pad was being underestimated. For bridges with steep vertical curves the load can be grossly underestimated. The slab pad load is now computed using a straight line approximate for the top of girder geometry. This results in a more accurate, and slightly conservative loading. See the Theoretical Manual for loading details.

• The controlling point for release strength is at the end of the prestress transfer length. PGSuper computes it at H from the end of the beam. A Point of Interest was added at the end of the prestress transfer length.
• PGSuper was applying the distributed traffic barrier loads to the wrong number of girders. The traffic barrier weight was divided by the correct number of girder lines, but it was applied to one additional girder line. For example, the traffic barrier weight is divided by 3 girder lines, but was applied to 4. This problem has been corrected.

• PGSuper used the SI version of the LRFD specifications for the HL93 Live Load Description regardless of the specification basis. PGSuper now uses the HL93 Live Load Description based on the currently selected specification basis.
• Added TxDOT Girder Schedule (IBNS) Report
• Added support for the Nebraska NU girder types
• Girder end distance can now exceed the bearing offset when defining a connection library entry
• PGSuper incorrectly added half of top flange width to de when computing live load distribution factors for exterior I-beams. This problem was introduced in Version 1.3. This problem has been corrected.
• The input for SIP deck panels was not checked for consistency. The sum of the cast depth and the panel depth must be <= to the "A" dimension. This problem has been fixed.

• When the computed shear strain, ex, exceeds 0.002, ex is set equal to 0.002. When this case occurs incorrect values for beta and theta are computed. When v/f''c is < 0.075 the row for v/f''c < 0.1.00 in Table 5.8.3.4.2-1 is used. These problems have been fixed
• Updated the PGSuper to reflect the change in methodology for estimating prestress losses at shipping. These changes are in accordance with WSDOT Bridge Design Memorandum 5-2002
• NEW FEATURE You can now enter your own live load distribution factors. Select Loads | Live Load Distribution Factors... and enter your values.
• NEW FEATURE Support for Stay-In-Place (SIP) deck panel systems was added to PGSuper.
• PGSuper has been upgraded for the 2002 Interim provisions. Changes to the following provisions have been incorporated into PGSuper:
  • Distribution factors for I Beams (4.6.2.2.1)
  • Distribution factors for U Beams (4.6.2.2.1)
  • Bursting Zone Resistance (5.10.10.1)
• The loss equation used for U-beams is incorrect. The equation for I-beams is used. This problem has been corrected.
• Updated the geometry for the trapezoidal open box girder to accomodate the current WSDOT standards

• The limiting capacity of over reinforced sections was being computed incorrectly (C5.7.3.3.1). When rectangular section behavior is present, the equation for flange section behavior was used. When flange section behavior is present, the equation for rectangular section behavior was used. This problem has been corrected.
• Incorporated provisions of LRFD specifications up to 2nd Edition, 1998 with 1999, 2000, and 2001 interims
• Changed the accelerator key for Update Now from Ctrl+U to F5. This change makes PGSuper more consistent with industry standards.
• An option to ignore live load distribution factor "Range of Applicability" criteria has been added to the project Design Criteria library entry.
• The method of defining harped strands at the harping point has been changed. WSDOT bundles harped strands at the harping point and PGSuper reflected this practice. However, others do not bundle the strands but rather maintain the strand spacing throughout the girder. The method for defining harped strands at the harping point has been changed to accomodate this situation.
• The dimensions of an intermediate diaphragm can now be zero. Girder library entries define the size of an associated intermediate diaphragm on the Misc tab. For girders that don''t use diaphragms, enter a dimension of 0.0 for the height and widith.
• The bursting zone check for LRFD 5.10.10.1 has been changed to a single service limit state check over the bursting zone length instead of a check based on stirrup spacing.
• Added a Bridge Geometry Report that contains the station, offset, and top of deck elevations at the intersection of the centerline of the girder and the bearing line.
• Fix problem with prestressing strand material properties when the SI units version of the LRFD Specifications is used.
• Update moment capacity calculations to be consistent with the procedures described in the PCI Bridge Design Manual.
• Added support for WSDOT''s new trapezoidal girder section

• PGSuper mistakenly used the effective prestress, fpe, when evaluating LRFD 5.8.3.5. The term on the left hand side of the equation requires fps, the stress in the prestressing steel at the time for which the nominal resistance of the member is required. This problem has been corrected. Supporting information in the PGSuper Theoretical Manual has been updated as well.
• The size of interior diaphragms for W42G, W50G, W58G where defined incorrectly in the Girder Library. The library and the project templates have been updated with the correct diaphragm sizes.

• The maximum girder weight was not checked by PGSuper. Section 6.2.3.G.3g of the WSDOT Bridge Design Manual specifies a maximum shipping weight of 200 kips. The Project Criteria library has been updated to include a maximum girder weight parameter. The maximum weight is now check during the transportation analysis.
• The location of the upper harp strand bundle was defined incorrectly in the girder library for W83G, W83MG, W95G, and W95MG. The upper bundle is 3" above the lower bundle.
• When computing ultimate moment capacity, sections with c/de > 0.42 are considered overreinforced. These sections may be acceptable if it can be show that sufficient ductility can be acheived (LRFD 5.7.3.3.1). The LRFD Commentary suggests a means to compute the minimum nominal strength for over reinforced sections. PGSuper now computes this suggested minimum capacity in accordance with C5.7.3.3.1. Because this computation is not a requirement of AASHTO LRFD, as it was in the Standard Specification, it is left to the engineer to determine if it is acceptable for a given section to be over reinforced. PGSuper simply makes the computation but does not draw a conclusion.
• PGSuper has performed analysis checks for long girder stability since Version 0.6. However, the effects of the lifting and transportation stages where not considered during design. The PGSuper Preliminary Girder Designer has been updated to consider lifting and transportation stages. The Designer now determines the minimum release strength, minimum 28 day strength, lifting loop location and truck support location in order to insure girder stability. To aid engineers in the design process, PGSuper now includes a Stability View that graphs the factors of safety for girder stability against various locations of lift points and truck support locations.

• The minimum confinement reinforcement in the Bursting Zone (5.10.10.1) was computed incorrectly. The values of Avb/S Min in the Bursting Zone Check Details chapter of the Details Report are incorrect. Even though the jacking stress, fpj was reported, the jacking force was actually used. This problem has been corrected.
• Changed lift angle criteria for lifting analysis. The previous value was 60 degrees. A vertical lift creates the worst case. The library entries and templates have been updated.
• The topic "Computing the A Dimension" in the Theoretical Manual contained some typographical errors in the equations. These errors have been corrected.
• For lifting analysis, the camber due to prestressing alone is computed relative to the bearing locations. This is incorrect. For this computation, the camber should be relative to the ends of the girder. This has been corrected.
• Under certain conditions, PGSuper would incorrectly report a "Pass" for the factor of safety against failure during lifting. Specifically, when the Factor of Safety against Failure (FSf) is less than the Factor of Safety against Cracking (FScr) FSf is taken to be equal to FScr. When this situation occurs, PGSuper would used the allowable Factor of Safety against Cracking in its evaluation of the Factor of Safety against Failure. The allowable FScr is 1.0 and the allowable FSf is 1.5. PGSuper would report a "Pass" if FSf was greater than 1.0, not 1.5. This problem has been corrected.
• The parameter Fe (F sub epsilon) was not reported in the Shear Details chapter of the Details Report. This has been corrected. Notes have been added to clarify when Fe is applicable and when it is applied to the shearing strain ex.
• The self-weight load of that portion of the traffic barrier supported by the girder end cantilevers was not modeled. This load is now included in the structural analysis model when appropriate.
• The equations that preface the Details of Minimum Transverse Reinforcement Spacing Check table in the Details Report were reported incorrectly. The maximum reinforcement spacing is the minimum of the two computed values, not the maximum. This was only a problem in the table heading. The correct maximum reinforcement spacing is reported in the table.
• PGSuper models the girder self-weight, slab weight, traffic barrier, and overlay loads that occur in the girder overhangs as concentrated shears and moments. In a typical bridge, the girder cantilever (the portion of the girder that overhangs the bearing) is quite short. PGSuper now ignores the moment if the length of the cantilever is less than the depth of the girder. For this situation, the cantilever is a deep beam and strut-and-tie, rather than flexural, behavior occurs. Refer to the Structural Modeling section of the Theoretical Manual for details.
• The girder overhang moments were computed incorrectly. The moment was computed as P*Loh, but should have been P*Loh/2. Refer to the Theoretical Manual for details regarding Structural Modeling and Analysis. This problem has been corrected.
• The table headings for live load reactions were labeled incorrectly. The Min/Max subheadings were reversed. This problem has been corrected.

• The skew correction factors where incorrectly reported in the Distribution Factors Details chapter of the Details Report. This problem has been corrected.
• The skew correction factor for live load moment distribution factors being computed incorrectly. This error only occurred with skew angles greater than 30 degrees and for computations based on the US version of the LRFD Specification. When computing c1, a value of 12.0ts^3 was used instead of 12.0Lts^3 in the denominator. This problem has been corrected.
• For left skewed piers, PGSuper was using negative skew angles when computing the skew correction factor for live load distributions. This problem has been corrected.

• In the Moment Capacity Details chapter of the Details Report, the value for Ae was reported incorrectly. Ae is equal to Beta1*Ac. This was only a reporting problem, the correct value for Ae was used in the analysis.
• For lifting analysis, the modulus of rupture was incorrectly based on f''c (28 day strength) rather than f''ci (release strength). This has been corrected.
• The allowable stress checks during transportation have been changed so that stress for a vertical girder with impact are considered separately from the stresses in an inclined girder without impact. This is consistent with the PCI Journal article this analysis is based on.
• Editorial changes to the lifting and hauling report details
• For lifting analysis, re-organized the way PGSuper compares the Factor of Safety Against Failure with the Factor of Safety Against Cracking. The check is now consistent with the PCI Journal article that the lifting analysis is based on.
• The maximum distance between supports for hauling analysis was not consistent with WSDOT criteria. The Design Criteria library entries have been updated. The proper value is 130 ft (40 m).
• The upward impact factor for hauling in the WSDOT SI Criteria was incorrect. The impact has been changed to 20% per the WSDOT Bridge Design Manual.
• When defining strand locations in a Girder library entry, PGSuper would incorrectly indicate an error if a strand location was exactly aligned with the edges of the web. This problem has been corrected.
• The basis for live load deflections have been added to the reports. Live load deflection is reported per lane of live load, including impact.
• The input values for lifting pick point locations and hauling support locations have been added to the reports.

• The input values for lifting pick point locations and hauling support locations have been added to the reports.
• After a design was performed, and accepted, the check boxes in the girder editing wizard that cause the prestress force to be the maximum allowed for the number of strands selected were left unchecked. This was not a functional error, but caused problems for some users who would later tweaked the design, and find that the prestress forces weren''t changing automatically. Now the check boxes are checked after a design attempt if the PGSuper designer selects prestress forces that are maximum values.
• The properties for Strands and Rebar were always reported using converted SI values. WSDOT has reverted to US units. Changed implementation so reports uses US units rebar and strands.

• In rare cases, the moment capacity solver was unable to find an equilibrium state within the desired tolerance (i.e., the net axial force for the final strain state was not quite zero, but were within 1% of each other). Problem was due to the tolerance in the Naaman area calculation method. The large tolerance caused the strain/force curve to become step-wise, making it impossible for the equilibrium solver to find a valid solution. This problem has been corrected
• Added automated regression testing feature to assist with Quality Control and Assurance.
• On-line help documentation on dealing with library entries and entry conflicts was confusing. We have re-written the documentation for this topic to present the concepts more clearly.
• Bridges on curved alignments would, under very rare circumstances, cause PGSuper to enter into an infinite loop. This problem as been corrected.
• We've added printing capabilities with calculation sheet border for the Bridge Model View and the Girder View. Also added calculation sheet-like border to print of analysis results view (graphs).
• Library Editor Program did not report an error when trying to save to read-only files. This could result in confusion to users. The Library Editor program now reports an error if you try to save to a read-only file.
• The input control for entering pier skews accepted bad data and incorrectly interpreted some data. For instance, input of the form "20L", would result in a 20 degree right skew. This problem has been corrected.
• For some conditions, a skew angle of 10 degrees left was reported as 350 degrees right. This problem has been corrected.
• On some configurations, the PGSuper file converter would not work. The routine that converts old PGSuper files was dependent on the Windows Scripting Host (WSH) components. WSH is not installed by default with Internet Explorer 4.01and the conversion routines would not run on systems without WSH. The PGSuper file converter has been updated so it no longer depends on the WSH.
• Provided additional information for "A" dimension calculations in the Theoretical Manual
• You were not able to enter the number of girders directly into PGSuper. Users had to step through available choices with a "spinner control". This has been updated. The valid number of girders is between 2 and 26.
• Combined the tables for load combination and limit state results. This significantly reduced the size of the Details Report.

• The stress check tables have been re-arranged so one table reports both tension and compression checks for top and bottom of girder. This makes the Details report a little bit smaller.
• It was possible to define a bridge with negative girders lengths. This would cause a crash during analysis. Code was added to check for negative girders length and catch them from the user interface. Users are now required to define a valid model before the analysis is performed.
• Detailed information for distribution factor calculations was not being reported. A distribution factors details chapter has been added to the Details report.
• Added Ytop Girder and Ytop Slab to section properties output. This will make it easier to figure out where St girder and St slab come from.
• A Loading Details chapter has been added to the Details Report. This new chapter reports the details of the dead loads applied to the various structural analysis models. This will help users verify force results
• The stirrup layouts for WSDOT standard girders have been updated to more accurately reflect the WSDOT standard girder plans.
• It was possible to type non-numeric data into grids in girder and diaphragm library entries. This could lead to unpredictable behavior of the software. Stronger data validation has been implemented for numeric entries in grids.
• Shrinkage loss calculations based on the US version of the LRFD Specification are incorrect. Losses were computed as 17 - 0.123H. The correct equation is 17 - 0.150H.
• Detailed information about the structural models generated by PGSuper was not provided in the reports. The Details Report now contains detailed structural modeling information. The modeling techniques are covered at length in the PGSuper Theoretical Manual.
• In the details report, the witness line for sacrificial depth in the slab dimension picture is obscured. This picture has been updated.
• The modulus of rupture was incorrectly computed for lifting and shipping analysis. The allowable tensile stress was inadvertently used for the modulus of rupture. The modulus of rupture is now computed correctly.
• The eccentricity due to sweep in long girder stability analysis is reported incorrectly. The value reported for es is actually es*Fo. The value reported for es has been corrected. This error does not effect the results of the analysis.
• The wrong concrete strength was used for computing the maximum spacing of transverse reinforcement per LRFD 5.8.2.7. The weaker of the slab and girder concrete strength was used. The girder concrete strength should have been used. This has been corrected.
• Detailed reports for the factor of safety for cracking for lifting and hauling did not report which flange governed for cracking. A column was added in the report table to indicate which flange (top or bottom) governs cracking and the impact direction which governs as well.
• Under rare conditions, the status of the "Compute Prestress Force" check box in the Girder Editing Wizard is not saved. This problem has been corrected.
• Factor of safety for cracking for lifting did not account for impact. The computations have been changed to use maximum stress due to impact to calculate cracking FS for lifting.
• On the Hauling tab of the Project Criteria dialog, the concrete strength for allowable tensile stress has been changed from f'ci to f'c. This was an incorrect label in the dialog. PGSuper continues to use f'c in the calculation of the allowable tensile stress.
• The "draw longitudinal rebar" setting in the girder elevation view setting dialog was not being correctly interpreted. This caused the longitudinal rebar to be displayed sporadically based on the other girder view settings.
• Equation 5.8.4.1-4 and minimum spacing requirements were not being checked for horizontal slab-girder interface shear. These checks have been added to PGSuper.
• Added capability to describe top flange stirrups. These stirrups are a spaced evenly along the length of a girder and are used to strengthen the slab/girder interface. These stirrups are needed in order to pass the requirements of provision 5.8.4, especially for deep girders.
• Added girder length to Input Summary report.
• The legend for the stress table in the Hauling Details chapter had a typo. The symbol for bottom fiber stress, downhill side is fbu. It should have been fbd.
• dv was computed incorrectly per 5.8.2.7. Specifically, the wrong value for h is used. PGSuper was using the girder depth for h. This is incorrect. h should be the girder depth plus the gross slab depth, less the sacrificial depth. Per Article 5.3, h is overall thickness or depth of a member. Shear capacity is computed on the basis of the composite section, therefore the depth of the section is slab+girder. dv and h are now calculated correctly. Bursting zone calculations still use h to be the girder height This is because bursting calculations are performed for the bare girder.
• Bearings of the form N|S dd mm E|W were not being accepted as valid input. This is a valid form of input. The problem has been corrected.
• PGSuper would crash when trying to open an older version file if the file was read-only. The PGSuper file converted was writing the converted file over the original file. The file converter has been changed to write converted files to a temporary location. This avoids the read-only problem, and it protects the original file. Converted files are not updated until the user saves the file.
• An error would occur when trying to move both piers down station in the bridge editor. Updated software to correct this problem.
• A table of contents feature has been added to the report view. This makes it much easier to navigate reports. To use, just click the right mouse button in the Report View and select Table of Contents from the pop-up menu. Custom tables of contents are generated for each report type.
• If you enter a straight alignment direction of N 59 59 59.9 E, leave the Bridge Description Dialog, and then return, you will see an alignment of N 90 00 00.1 W. This problem has been corrected.
• PGSuper would accept the following bearings as valid input: N -90 E and N 34 34 -34 E. This problem has been corrected.
• The program was crashing in cases where there was a curved horizontal alignment was defined and the bridge lied entirely outside of the curve. This problem has been corrected. Bridges can now lie on either side of the curve. However, bridges still can NOT straddle between the ends of the horizontal curve and the straight tangents. This situation is not covered by the LRFD simplified distribution factor calculations.
• Reports were being completely reloaded after each results calculation. This caused all report windows to scroll back to the top, which is a nuisance to users Report views now retain their position after recalculations.
• Excess camber was being calculated incorrectly. Excess camber is defined as the total camber - screed camber. The program was calculating it as the total camber - slab deflection. This problem has been corrected.
• If the Version of the LRFD code was changed for the currently selected project criteria entry, the change would not be reflected in the output. The program has been fixed so that output will be automatically updated when the LRFD specification version is changed.
• The Shear Designer could create designs where the bar spacing exceeds the zone length. This would then cause an error message to be displayed in the girder editor. This problem has been corrected.
• The material-related constant Beta1 used in the moment capacity analysis was assumed to be equal the the Beta1 value for the slab - even if a portion of the girder was in compression. This could lead to non-conservative results for the c/de ratio. PGSuper now uses Beta1 based on the average Beta1 calculated for all materials on the compression side of the neutral axis. Beta1 is computed using Equation 8.2.2.5-6 of the PCI Bridge Design Manual.
• The allowable tensile stresses for lifting and hauling have been updated.
• The deflection computed due to harped prestressing strands was computed incorrectly. Equation 5 from the PCI Design Handbook was used. When coding this equation into the software, we missed the fact that this equation is the case of the prestressing force acting through the C.G. of the girder at the girder ends. Generally, this is not the case. The implementation has been updated to include the effect of the harp strand prestress force being eccentric.
• When the prestressing strand type is changed in the Bridge Description dialog the jacking force for the prestressing strands was not updated. This problem has been corrected. Now, in the Girder Editing Wizard, if you check the boxes for PGSuper to compute the prestressing force, and you subsequently change the strand type, the prestressing force input will be changed to reflect the change to the strand type.
• Details for the horizontal shear capacity calculation were not available in reports. A new details section was added to the Details Report and simplified summary report for horizontal shear capacity.
• Under certain conditions the prestressing force was not initialized properly in the girder editing dialogs. As a result the wrong prestressing force was used in analysis. This problem has been corrected.
• The equation for the lateral cracking moment reported in the lifting and shipping analysis details was incorrect. The term (fr + ft) should have been (fr - ft). Even though the PCI papers by Mast and Seguirant use '+', the sign convention used by PGSuper requires '-'. This was only an error in the report, the correct equation is used when computing the lateral cracking moment
• The girder deflection for camber was computed incorrectly. The girder deflection for camber is computed using the final span length and the initial concrete properties. The final span length is used, because WSDOT specifies that precast girders are supported at their final bearing location after the girders have been removed from the casting beds. The stiffness of the girder is Ig*Eci. Internally, PGSuper computes the initial deflection for camber as the final deflection multiplied by the ratio Ec/Eci. Originally, PGSuper used the ratio Eci/Ec. This defect has been corrected.
• Elastic shortening losses were computed incorrectly. Specifically, the prestress force at transfer was computed as the prestress force prior to transfer instead of the prestress force after transfer. This problem has been corrected.
• Modulus of rupture calculations [5.4.2.6] based on the US version of the LRFD Specification are incorrect. The coefficient multiplied with the square root of the concrete strength was incorrect.
• The normal force between the slab and girder used in horizontal shear capacity calculations was calculated incorrectly. The load included diaphragm loads and sacrificial slab material and did not account for the haunch. The diaphragms are applied to the structure prior to slab casting and do not contribute to the slab/girder interface load. Overlay load is not used because overlays are temporary. PGSuper has been modified such that the diaphragm and sacrificial slab depth do not contribute to the normal force on the girder/slab interface and the haunch weight is now applied to the interface.
• Correct typo in Bridge Site Stage headings in Moments, Shears, and Reactions report.
• The definitions for load cases DC and DW were not well-defined for individual bridge stages. Notes have been added to the details report which define loads (slab, girder self weight, etc.) belong to the LRFD load cases for a given stage.
• Locations for results tables were not well-defined. It was difficult to tell whether the location was measured from the end of girder, or from the left support. Notes have been added to the location labels which fully describe the datum for the Location column.
• Added tenth point indicators to the Location field in the report tables
• If you try to save a read-only input file, the program responds with an error saying that the "file could not be found". This does not help determine the real cause of the problem. PGSuper was changed so the program does not attempt to save read only files. Instead it reports to user that he must save under a different name.
• The modeling of the end diaphragms has been made more flexible. When using PGSuper to model an interior span of a multi-span structure, the girders typically bear onto the diaphragms, rather than the girders supporting the weight of the diaphragms (as was originally assumed by PGSuper). You can now specify how and where the end diaphragm load is applied to the structure.
• New Feature: Girder Schedule Report. This report contains a table very similar to the Girder Schedule defined in the WSDOT standard girder plans. The report may or may not be useful for agencies outside of WSDOT. To access the report, select View | Reports, and from the Reports dialog, select "Girder Schedule Report".

• The EVC (end of vertical curve) station was reported incorrectly in the Profile Details table. This has been corrected.
• The allowable tensile stress for the Casting yard stage was incorrect for US units version of the project criteria. This has been corrected.
• The creep coefficient was not computed correctly using equation C5.4.2.3.2-1 of the LRFD specification. This error has been corrected.
• The girder cross section dimensions have been updated for W74MG and W83MG girders.
• Cracking moment was computed incorrectly. The correct equation is Mcr = (fr+fpb)Sbc - Mdnc(Sbc/Sb-1).
• The comparison between 1.2Mcr and 1.33Mu is incorrect. Per LRFD 5.7.3.3.2, Mr Min should be the lesser of 1.2Mcr and 1.33Mu. The greater of these values was being reported. This has been corrected.
• The allowable tensile stress for hauling was incorrect. This has been corrected.
• The schematic picture for the slab geometry, the lower witness line for the "A" dimension does not display correctly. The picture has been updated to show witness line more clearly.
• In version 0.88, we upgraded to the new Microsoft MSXML parser for reading input files. This parser is a true XML parser and has problems with special characters such as &,<,>,", and "s. This caused input files with object names or properties using any of these special characters to become invalid xml and be rejected. In short, PGSuper can no longer read input files containing these characters. The file loading and saving routines have been updated to deal with these special characters correctly. However existing files with special characters will still cause problems. If you have problems reading old input files when upgrading to version 0.88, search for any of the above-mentioned special characters and delete them or replace them with valid alphanumeric text.
• The picture for camber details is incorrect. The Dslab on the right side of the graph should be Ds. Also, Ds should be defined as Screen Camber. The picture has been updated to show variables more clearly.
