摘　　要：提出了一种新型抗冲切钢筋双钩筋 ,并通过试验证明了其良好的抗冲切性能 .在对 5个配双钩筋板柱连接试件的试验结果进行详细介绍与分析之后 ,讨论了双钩筋直径、肢数及布置对试件抗冲切承载力的影响 ,并根据试验资料给出了承载力计算公式 。A new form of shear reinforcement,called double hooks,is presented in this paper.Its good behavior in punching resistance is verified by experiments.Five concrete slab column connections with double hooked stirrups are analyzed.The diameter,nummer of layer and layout of the stirrups in slab are discussed as influential factors.Based on analysis and tests,expressions to predict the strength of such shear reforced concrete slabs are proposed.Rules on the layout of shear reforcement are all recommended.
