摘　　要：钢板剪力墙具有承载力高、延性好、耗能能力强等优点,将抗震性能优越的钢板剪力墙用于钢管混凝土框架中形成钢管混凝土框架-钢板剪力墙结构体系。对这种组合结构体系和钢管混凝土框架在滞回荷载作用下的性能进行试验研究,研究结构体系的承载力、延性和耗能能力等指标,分析钢板剪力墙对结构体系的承载力和耗能能力的提高幅度;同时采用有限元软件分析结构体系的性能,有限元计算结果和试验结果吻合较好,验证有限元分析模型的正确性。研究结果表明:钢板剪力墙具有较高的承载力、良好的延性和优越的耗能能力,和钢管混凝土框架具有良好的协同工作性能,钢板剪力墙的存在显著提高结构体系的承载力和耗能能力;在该文分析的结构体系中采用混合杆系模型可以较好模拟钢板剪力墙的滞回性能,结构体系分析模型也为钢管混凝土框架-钢板剪力墙结构体系在实际工程中的应用提供参考。Steel plate -shear wall （SPSW） structures have many advantages, such as high load-carrying capacity, good ductility and excellent energy dissipation capacity. When the SPSW is used in the concrete-filled steel tube frame, a new kind of composite structure （composite frame-SPSW system） appeares. The behaviors of composite frame-SPSW system and composite frame are introduced. Based on the experimental results, the function of SPSW to the composite frame was studied. A simplified model is developed for SPSW. The analysis results by the finite element software agree well with the experimental results, which proves the effectiveness of the proposed model. The research results show that SPSW structures exhibit high load-carrying capacity, good ductility and excellent energy dissipation capacity. The application of SPSW wall can increase the load-carrying capacity and energy dissipation capacity of composite frame evidently. The Combined Strip Model is effective in modeling the hysteretic behavior of SPSW. Those results can provide reference for the application of composite frame-SPSW system.
