摘　　要：将屈曲约束钢板墙作为抗侧力构件和耗能构件应用于钢筋混凝土框架结构,即形成混凝土框架-屈曲约束钢板墙结构体系。目前对这类结构在水平荷载作用下的位移限值并未进行研究,规范也无相关规定。利用模型试验和数值模拟的方法,对混凝土框架-屈曲约束钢板墙结构的受力性能进行了研究。分析了这种新型混合结构体系的受力过程与受力特点,并给出了弹性和弹塑性层间位移角限值的建议取值。建议混凝土框架-屈曲约束钢板墙结构的弹性层间位移角限值取为1/600,弹塑性层间位移角限值取为1/50。Buckling restrained steel plate shear wall（ BRSPSW） can be used in reinforced concrete frame structure as lateral load resisting component and energy dissipating component. For this kind of new hybrid structure system,no research work on drift limit under lateral load has been conducted and there is no relevant specification. Using model test and numerical simulation method,the mechanical performance of reinforced concrete frame with buckling restrained steel plate shear wall was studied. The loading process and mechanical characteristics of reinforced concrete frame with buckling restrained steel plate shear wall was analyzed,and the elastic and elasto-plastic drift limit were proposed. It is suggested that the elastic and elasto-plastic inter-story drift limit of reinforced concrete frame with buckling restrained steel plate shear wall is 1/600 and 1/50 of the story height respectively.
