摘　　要：阐述了预制钢筋混凝土剪力墙结构接缝性能研究的重要性和最新进展。综述了国内外预制钢筋混凝土剪力墙结构接缝连接的设计规范及设计方法,并在此基础上指出预制装配式钢筋混凝土剪力墙结构的水平接缝和竖向接缝是结构的关键部位。水平接缝传递竖向荷载、承受水平剪力;竖向接缝确保预制剪力墙墙片之间的相互作用,影响结构的变形和耗能能力。水平接缝处竖向钢筋的有效连接,或将部分竖向接缝设计成装配式耗能连接接缝,将有效提高结构的抗震性能。水平接缝处竖向钢筋的有效的连接方法、构造措施,及装配式接缝的耗能性能有待于进一步研究。The importance of study on seismic behavior of joints in precast RC shear wall structures was expounded and the progress of investigation on seismic behavior of ioints in precast RC shear wall structures was introduced. The design code and design method of joints in precast RC shear wall structures at home and abroad were also summerized. It is concluded that horizontal joints and vertical joints are important parts of precast RC shear wall structures. Horizontal joints transfer vertical load, bear horizontal shear force. Vertical joints transfer shear force be- tween the precast shear walls, and affect the structure deformation and structural energy dissipa tion capacity. It is suggested that more attention should be paid to the construction measure, connection method of vertical bars across horizontal ioints and energy dissipation behavior of assembled vertical joints in future research work.
