Tests were carried out to study the effect of stirrups and draped reinforcement on the shear strength of prestressed concrete beams. Tests of 104 simply supported beams are discussed. The principal variables were the amount, type, and spacing of the stirrups and the profile of the longitudinal reinforcement. Other variables included the shape of the cross section, the prestress level, the amount of longitudinal reinforcement, the concrete strength, and the type of loading. The patterns of behavior observed in the tests are classified and compared with special attention to the manner in which inclined cracking developed and the mode of failure.
