An experimental investigation of the shear behavior of 7 bonded post-tensioned ultra-high strength prestressed concrete test beams with stirrups were tested. The effects of the shear span-depth ratio, the stirrup ratio, the grade of concrete strength and the degree of prestress on model of failure and diagonal crack-resistant capacity and shear capacity were analyzed. The shear mechanism of ultra-high strength prestressed concrete test beams was analyzed. The applicability of existing formulas for shear capacity calculation of ultra-high strength prestressed concrete beams with stirrups is investigated. The research achievements will provide an engineering application of ultra-high strength prestressed concrete test beams with stirrups.
