基于不同隔震层位置的结构隔震对比

目前隔震技术在我国已经得到广泛应用,隔震层的位置布置也变得比较灵活.本文设计的框架-剪力墙结构,研究了在基础隔震与层间隔震情况下的不同的隔震效果.使用SAP2000对其进行非线性结构分析,得到了不同隔震层位置对应的层间剪力、层间位移、相对加速度,比较两种隔震方法的隔震效果,发现结构在不同的隔震层位置时对应不同的反应.

THE ISOLATION EFFECT COMPARISON BASED ON THE POSITION OF ISOLATION LAYER

Currently isolation technology is widely used in our country,the layout of the isolation layer is also becoming more flexible.A seven-story frame structure is an example in this paper,base isolation and story isolation is studied on the isolation effect.We use the large-scale structural finite element analysis software SAP2000 to make a nonlinear structure analysis,and we can get differeent isolation layer position corresponding to the？ story shear force,story drift,relative acceleration,compare two methods of isolating effect,we find that the influence of different isolation layer position on structure is different.
