摘　　要：在板柱结构中,板柱连接处的冲切问题是结构设计中的一个薄弱环节。基于近年来国内外对板-柱结构中抗冲切锚栓的研究成果,提出了抗冲切锚栓配筋形式优于传统箍筋及弯起钢筋配筋形式的意见;并对5种国内外配置抗冲切锚栓的混凝土板受冲切承载力计算方法进行比较分析;最后结合某工程实例,探讨了板-柱结构抗冲切锚栓设计中应注意的一些问题。同时对现行《混凝土结构设计规范》中受冲切承载力计算的章节,提出了补充有关抗冲切锚栓计算公式的建议。Proportioning of slab-column connections for adequate Punching strength and ductility is a trigger mechanism in the design of reinforced concrete flat plat structures. Based on the domestic and international research findings, the conclusion is drawn that higher strength and more ductile behavior are achieved compared with traditional stirrup and diagonal shear reinforcement. Through the comparative analysis about the domestic and international computational model of stud shear reinforcement for con crete slab, combining the engineering practice, the rules to design and details to stud shear reinforcement in accordance with China Code （GB50010） are proposed.
