原始语种摘要: This paper describes an experimental study of the punching resistance of unbonded post-tensioned slabs with shear reinforcement. Seventeen slabs 200 mm (7.87 in.) thick and 3.0 m (9.84 ft) square were loaded at their centers and simply supported near their edges. Fifteen contained shear reinforcement in the form of stud rails and the principal variables in the series were those of the shear reinforcement. The behavior of the slabs and the strains of the shear reinforcement are described in some detail. The treatment of ultimate strength is limited to showing the effects of the principal variables of the shear reinforcement.
