| 摘 要： | 运用有限元分析软件SAP2000对某偏心钢框架和在原框架基础上设置防屈曲支撑的3种方案进行了模态分析和时程分析，比较了它们的周期比、位移比及层间位移等．结果表明：合理地设置防屈曲支撑可以有效的控制偏心结构的扭转效应，并减小结构的侧向水平位移和层间位移；在大震下，能够降低结构的加速度反应，耗散大部分地震能量，保护主体结构．

| Abstract: | In this paper,based on finite element analysis software SAP2000,an eccentric steel frame was compared with three kinds of control plans with buckling-restrained braces in mode analysis and time history analysis,comparing period ratios,displacement ratios and inter-story displacement.The results show that the torsional deformation of the structure can be controlled effectively.Besides,horizontal displacements and story drifts are reduced.Further,the acceleration responses are decreased,and buckling-restraine... |
