Fatigue and Shear Behavior of HPC Bulb Tee Girders

摘要

The objectives of the research were (1) to provide assurance that full size, deep prestressed concrete girders made with HPC would perform satisfactorily under flexural fatigue, static shear, and static flexural loading conditions; (2) to determine if a higher allowable concrete tensile stress can be used in the flexural design of high strength prestressed concrete girders; and (3) to investigate the use of welded wire deformed reinforcement as an alternate to deformed bars for shear reinforcement.
