Prestressed concrete t-beams have complex shear mechanism, and their shear performance is influenced by various factors, such as flange width and prestress. The shear performance of prestressed concrete t-beams has not been solved completely. This study designed and established nine prestressed concrete t-beams and one ordinary reinforced concrete t-beam to investigate the influence of flange width and the number and bending angle of prestressed tendons on the shear bearing capacity of concrete t-beams. The crack development, failure form, mid-...
