摘　　要：本文探讨配置抗冲切钢筋的混凝土板在中心柱荷载作用下可能出现的各种破坏形态及相应的承载力，并提出按最薄弱可能原则确定板的实际破坏形态与承载力的概念和方法，研究结果得到了试验验证，为板的抗冲切配筋设计提供了正确的理论基础。This paper deals with concrete slab-column connections with punching shear reinforcement.Their various possible modes of failure under axial column loads are described with theircorresponding load-carrying capacities analyzed- It is put forward that the real failure mode andstrength should be determined by the principle of weakest possib1e mode. Based on the conceptand formulae proposed in the paper, the theoretical estimation of both ultimate strength andfailure mode agrees well with the test results.
