PGSuper  3.1
Precast-prestressed Girder Bridges
Closure Joints

Define project criteria for specification compliance checking of cast in place closure joints used with spliced girders.

NOTE: These parameters use used by PGSplice only.

The parameters on this tab are allowable stress limits. They can be set to match or deviate from AASHTO.

Stress Limits for Temporary Stresses before Losses (LRFD 5.9.4.1, 5.14.1.3.2d)

The information in this section allows you to deviate from LRFD 5.9.4.1 and 5.14.1.3.2d.

Item Description
Compressive Stress Enter the coefficient for the allowable compressive stress.
Tensile Stress in the Precompressed Tensile Zone - In areas without minimum bonded auxiliary reinforcement Enter the coefficient for the allowable tensile stress.
Tensile Stress in the Precompressed Tensile Zone - In areas with minimum bonded auxiliary reinforcement Enter the coefficient for the allowable tensile stress.
Tensile Stress in other areas - In areas without minimum bonded auxiliary reinforcement Enter the coefficient for the allowable tensile stress.
Tensile Stress in other areas - In areas with minimum bonded auxiliary reinforcement Enter the coefficient for the allowable tensile stress.

NOTE: See Longitudinal Reinforcement in the Technical Guide for discussion describing how longitudinal reinforcement in the girder factors into the determination of the allowable tensile stress.
