【提要】  锚栓在提高板柱连接的强度和延性方面具有优良的性能。为了考察锚栓的抗冲切性能,进行了三个配置锚栓和传统箍筋的板冲切对比试验。试验表明锚栓比箍筋更能有效地提高板的抗冲切能力和改善板柱连接的延性。根据国内外试验资料,探讨并提出了抗冲切锚栓的设计构
造措施,同时结合我国现行《混凝土结构设计规范》(GB50010—2002)提出了配置锚栓的板抗冲切设计方法。所提出的公式的计算值与试验结果符合较好,并具有一定的安全度,可供采用锚栓进行抗冲切设计时参考。

Design of Studshear Reinforcement for RC Slabs/Liu Wenting,Huang Chengkui(State Key Lab. of Coastal & Offshore Engin., Dalian University of Technology,Dalian 116024, China)
Abstract:Three specimens for slabcolumn connections with stirrup and studshear reinforcement are tested.Test results reveal that studshear reinforcement is more efficient than stirrups in increasing strength and ductility of slab.Based on the tests presented earlier domestically and abroad,rules to design and detail studshear reinforcement in accordance with China Code GB50010—2002 are presented.
