PGSplice™ Known Problems
No matter how hard we try, no software is perfect. In order to keep you informed of problems that might effect your designs we publish this list of known problems. However, we don't stop here. Interim (or preview) updates to the software are published as quickly as possible to provide you with the latest enhancements and fixes. Be sure to check out the download area to get the latest version of the software.

Topic: Anchor set loss computed incorrectly.
Version: 6.0
Date: May 03, 2021
Version Corrected: 6.1
Description: The anchor set loss is computed incorrectly. The predicted length of the zone affected by retraction of post-tension tendon during seating is twice what it should be resulting in twice the anchor set loss. We are actively fixing this issue and will have an updated version of the software available within two weeks.
Resolution: Anchor set loss calculations have been corrected. Updating to version 6.1 is recommended.

Topic: Post-tension secondary effects not computed for U-Beams with multiple stages of tendon stressing
Version: 4.1.5
Date: January 16, 2020
Version Corrected: 4.1.6
Description: Secondary post-tensioning effects are not computed for the second stage of tendon stressing for spliced U-Beam bridges with multiple stages of post-tensioning. This problem only occurs with spliced U-Beams bridges with multiple stages of post-tensioning.
Resolution: Version 4.1.6 fixes this problem.

Topic: The net compression force at the slab-girder interface for interface shear resistance does not use the correct load factor.
Version: 4.1.5
Date: October 23, 2019

The net compressive force on the slab girder interface, Pc in LRFD Equation, is overstated. The net compressive force is taken to be the weight of the deck, less the weight of the sacrificial wearing surface. The DC limit state load factor is not applied.

Verify interface shear capacity by hand calculation. The necessary information can be found in the Horizontal Interface Shear chapter of the Details report. In the third table of the subsection titled "Details for Horizontal Interface Shear Capacity (Strength I)[]" re-compute the interface shear capacity found in the column labeled "c acv + u[avf fy + pc]" using a conservative value of 0.0 for pc as suggested by AASHTO LRFD BDS C5.7.4.3.

Topic: Bottom of girder elevation at temporary supports is reported incorrectly
Version: 4.1.2
Date: May 22, 2019
Version Corrected: 4.1.3

The bottom of girder elevation at temporary support in the Bridge Geometry report are reported incorrectly. The haunch depth, rather than the slab offset is deducted from the deck elevation.

Deduct the slab thickness from the reported elevation to get the correct elevation.


The version 4.1.3 release corrects the bottom of girder elevation at temporary support.
