摘　　要：底部大空间建筑在形式上可以提供灵活的布置空间,同时具有较好的经济效益,从而日益受到人们的青睐,但"上刚下柔"是这种结构形式的一个弱点。本文通过对底部大空间结构安装阻尼器后进行非线性地震反应分析,与原结构对比得出阻尼器可以减小底部大空间结构的位移,具有很好的减震效果,从而使底部大空间结构的应用范围更广。本文得出的相关结论可供设计参考。The building of the large space at bottom can provide a flexible arrangement of space and also has good economic efficiency.Thereby this kind of structure has been increasing interested by people.But ＂ upper rigid and lower flexible＂ is one of the weaknesses of it.In this paper,based on non-linear seismic response analysis of the installation of dampers in the structure of the large space at bottom and the comparison with original structure,the conclusion was obtained that damper has very good damping effect as it can reduce the displacement of the structure,which could broaden applicable scope of the structure with large space at bottom.The conclusions of this paper can be refered in design.
