Shear Behavior and Capacity of Large Scale Prestressed High Strength Concrete Bulb -Tee Girders

Abstract

Based on the measured test results, an analytical model, Crack Displacement Field Theory (CDFT), was developed for predicting the shear response of prestressed/reinforced concrete members. Compared to other existing models, it could capture the discrete displacement due to crack opening and crack slip along crack surface and can take account the variation of stresses in reinforcement due to bond. Good agreements were achieved between the model predictions and test results.
