The technology of prestressed concrete is widely used in structures, prestressed concrete t-beams have complex shear mechanism which is influenced by various factors and not been solved completely. In order to study the influence of flange width, number and bent-up angle of prestressed tendons on the shear bearing capacity of concrete t-beams, nine prestressed concrete t-beams and one ordinary reinforced concrete t-beam were designed and manufactured. The crack development, failure pattern, mid-span deflection, concrete strain, stirrup strain a...
