摘　　要：将1层钢框架增设于原6层钢筋混凝土框架之上,并在形成的整体框架中布设支撑。讨论防屈曲耗能支撑的设计方法,利用有限元分析软件计算在多遇地震和罕遇地震作用下的整体结构性能并进行比较分析。分析结果显示:采用支撑后,可以改善整体框架的工作状态,改善框架的扭转情况,有效控制框架的层间位移。The buckling restrained braces were erected on the integral frame consisted of six stories reinforced concrete frame and one story steel frame added at the top. The design of buckling restrained brace was discussed. The performance under frequent earthquake and rare earthquake of the integral structure was calculated and comparatively analyzed by finite element software. The analysis showed that the working performance and the frame torsion were improved,interstory displacement of frame was controled effectively by using the buckling restrained brace.
