[摘要] 利用SAP2000軟件建立包含和不包含屈曲約束支撐的鋼筋混凝土框架計(jì)算模型，分別采用反應(yīng)譜分析和Pushover分析方法對(duì)兩種模型進(jìn)行對(duì)比計(jì)算分析。結(jié)果表明：在純鋼筋混凝土框架結(jié)構(gòu)中合理設(shè)置屈曲約束支撐，可以達(dá)到增加框架結(jié)構(gòu)的側(cè)向剛度、明顯降低結(jié)構(gòu)側(cè)向變形、實(shí)現(xiàn)多道設(shè)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
