建筑隔震结构的地震反应分析

Seismic Response Analysis on Base Isolated Structure

以某配电楼工程为背景,采用有限元软件ANSYS对其在隔震与不隔震两种情况下的地震反应进行了分析,结果表明,采用隔震技术可显著降低上部结构的地震反应。结构在地震作用下的位移主要出现在隔震层,上部结构发生的变形很小。从而验证隔震技术的有效性。

The seismic response of the isolated and non-isolated power distribution building under quake is investigated in this paper with the FEM software ANSYS. The results indicate that the seismic response from the upper structure of the base-isolated building is greatly reduced. The results are also show that structural displacements mainly appears in the isolated layer, and the deformation of super structure is small, which testifies the efficiency of isolated technology.
