摘　　要：对3个配置抗冲切箍筋的钢筋混凝土板柱边节点进行低周反复荷载作用下的抗震试验研究,分析了板柱边节点的破坏过程和破坏形态,并对配置抗冲切箍筋的板柱边节点的抗震性能进行了评价。试验结果表明:配置抗冲切箍筋的板柱边节点可以达到中等延性水平,变形能力满足规范要求。配置抗冲切箍筋较配置拉筋的板柱节点抗震性能好,且加密抗冲切箍筋能较好地抑制板筋平面外屈曲。Three RC column-slab edge connections with resisting punching shear stirrups were tested under cyclic loads,in order to study the cracking process, failure mode and seismic performance. Test results reveal that lateral drift capacity of column-slab edge connections with resisting punching shear stirrups can meet the code＇s requests. Column-slab connections allocated with punching shear stirrups show better seismic performance than those configure stretch. Resisting punching shear stirrups have the function of controlling the outside buckling of the flexural reinforcement.
