The Hauling View provides the parameters for hauling analysis as well as the hauling analysis report. Use the input fields on the left side of the view to define the specific parameters of a hauling analysis. The report on the right side of the view will automatically update as the analysis parameters change.

Analysis is performed for two cases; Normal Crown Slope and Maximum Superelevation.

Effective Prestress Force at Lifting (Fpe)

Enter the effective prestress force at the time of hauling. If the Prestress Definition in the Girder View is set to Simplified, enter the effective prestress force in the straight, harped, and temporary strands. If the effective Prestress Defintiion in the Girder View is set to Detailed, press [Edit Fpe] and enter the prestress force and its location relative to the top or bottom of the girder.

Material

Enter the girder material at the time of hauling.

Item	Description
f'c	Concrete strength
Ec	Modulus of elasticity. If this box is checked, enter a value, otherwise the modulus of elasticity will be computed
fr	Modulus of rupture. Enter the coefficient for computing the modulus of rupture
K1, K2	Averaging and bounding factor used when computing the modulus of elasticity

Analysis Parameters

Enter the analysis parameters

Item	Description
Trailing Bunk	Distance to the bunk point at the trailing end of the haul configuration
Leading Bunk	Distance to the bunk point at the leading end of the haul configuration
Impact Up/Down	Dynamic load allowance (impact). Select how the impact loading is to be applied. It can be applied to the normal crown slope case, the maximum super elevation case, or both.
Normal Crown Slope	Enter the normal crown slope
Max. Superelevation	Enter the maximum expectied superelevation to be encountered during the haul
Wind Loading	Select the wind loading type and enter the loading parameters. For Wind Speed, enter the wind velocity and wind pressure will be comptued according to LRFD 3.8.1.2. For Wind Pressure, enter a pressure loading applied to the vertical surface of the girder.
Centrifugal Force	Select the centrifugal force type; Favorable or Adverse. Favorable forces act away from the center of the turning movement while Adverse forces act inwards.
Speed	Enter the turning speed
Turning Radius	Enter the turning radius
Camber	Select the method for accounting for camber. For the offset method, the center of gravity of the girder is adusted by a percentage to allow for camber. For the direct method, an actual camber is input
Haul Truck	Select a haul truck from the drop down list or select "Define haul truck" to input the haul truck parameters
Height of girder bottom above roadway	Enter the location of the bottom of the girder from the roadway surface directly above the roll center
Height of roll axis above roadway	Enter the location of the roll axis above the roadway surface
Truck Roll Stiffness	Enter the roll stiffness of the haul truck
Truck Width	Enter the center to center width of the truck wheels
Sweep Tolerance	Enter the girder lateral sweep tolerance
Support Placement Tolerance	Enter the lateral tolerance for placement of the bunking devices.

Criteria

Define the analysis criteria

Item	Description
Factors of Safety	Enter the factors of safety against cracking and failure
Evaluate stresses	Select the method for computing and evaluating stresses in the girder. Stresses computed for a plumb girder do not account for the tilt of the girder into its equilibrium position. Stresses computed for a tilted girder account for the girder tilting into its equilibrium position.
Compression	Enter the coefficient for computing allowable compression
Tension	Enter the coefficients for computing allowable tension with and without sufficient bonded reinforcement. There are allowable tension limits for the Normal Crown Slope and Maximum Superelevation cases
Max. distance between bunk points	Enter the maximum permissible distance between bunk points
Max. leading overhang	Enter the maximum leading overhanging
Max. girder weight	Enter the maximum girder weight that can be hauled.
