Relaxing Shear Stress Limit for the End Region of Prestressed Concrete Girders

Abstract

AbstractThis paper investigates the potential for relaxing the 0.18fc′ shear stress limit imposed by AASHTO load-and-resistance factor design (LRFD) in the end regions of prestressed concrete girders with relatively large bottom flanges, which often exceed this ...Practical ApplicationsShear stress in the end regions of prestressed concrete bridge girders is a critical design consideration, particularly when girders are not cast integrally with supports. Current design codes conservatively limit this stress to 0.18fc′ to ...
