摘　　要：本文以实际工程为研究背景,根据模型相似关系,通过拟动力试验的方法,对钢筋混凝土框架-剪力墙模型结构的滞回反应和耗能进行了分析,探讨了结构在地震作用下的破坏机理及其薄弱环节或部位。试验结果表明,在水平地震作用下,框架-剪力墙结构的屈服顺序为:剪力墙根部→框架各层梁端→框架各柱根部,剪力墙的屈服和耗能能力对整个结构的承载力和变形性能影响很大。当弹塑性变形较大时,结构的性能主要取决于剪力墙根部截面的性能。本文工作为指导这类结构体系的抗震设计以及进行更深入的研究提供了基础资料。Pseudo dynamic test was conducted on a model frame wall structure which was constructed based on an actual prototype structure. Hysteretic response and analysis of energy dissipation capacity of the frame-shear wall model structure was studied, with emphasis on damage mechanism and weak points of structure under earthquake loading showed that yielding took place in the order from the base of the shear wall to the ends of the frame e ~ The experimental results lements. The strength and energy dissipation capacity of the shear wall had great influence on that of the total structure. The seismic performance under large deformation is mainly dominated by the deformation of the shear wall. The study contributes to the literature for developing future design guidelines.
