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.Keywords: column-slab edge connection; resisting punching shear stirrup; seismic performance; experimental study作者简介:张蕾,本科,高级工程师,Email:850680715@qq.com。参考文献[1]段洪涛.钢筋混凝土板柱节点抗震性能的试验研究[D]. 重庆: 重庆大学,2004.[2]JGJ 101—96建筑抗震试验方法规程[S].北京:中国建筑工业出版社,1996.[3]周朝阳.冲切与弯曲和剪切的比较分析[J].工程力学,1997,14(A02):391-394.[4]唐九如.钢筋混凝土框架节点抗震[M].南京:东南大学出版社,1989.[5]刘文珽,黄承逵,姚谦峰.混凝土T形边柱板柱连接抗震性能试验研究[J].建筑结构学报,2009,30(2):47-54.[6]ACI-ASCE Committee 325.Recommendations for design of slab-column connections in monolithic reinforced concrete structures[J].ACI Structural Journal, 1988, 85(6):675-696.[7]GB 50011—2010建筑抗震设计规范[S].北京:中国建筑工业出版社,2010.[8]GB 50010—2010混凝土结构设计规范[S].北京:中国建筑工业出版社,2011.[9]SAMI MEGALLY, AMIN GHALI.
