[摘要] 利用SAP2000软件建立包含和不包含屈曲约束支撑的钢筋混凝土框架计算模型，分别采用反应谱分析和Pushover分析方法对两种模型进行对比计算分析。结果表明：在纯钢筋混凝土框架结构中合理设置屈曲约束支撑，可以达到增加框架结构的侧向刚度、明显降低结构侧向变形、实现多道设防的效果。

Abstract: Computer models of buckling restrained braces-reinforced concrete frame and RC frame were set up, and seismic performances of the models were calculated by adopting response spectrum analysis and Pushover analysis based on SAP2000. The results show that the RC frame including buckling restrained braces will increase story-stiffness, decrease lateral deformation of frame structure significantly, and reach requirement of more defences in seismic concept design of buildings.

Keywords: RC frame; buckling restrained braces; seismic response analysis
