层间隔震结构地震反应分析

层间隔震是一种新的隔震设计思想,它将隔震层设置在建筑物某层柱子和楼板之间进行结构的地震反应控制。介绍了层间隔震在某一工程中的应用,采用ETABS有限元分析程序对其进行了动力非线性时程分析,计算结果表明:层间隔震能有效降低结构的地震反应,隔震层的变形控制在安全的范围之内。

Earthquake Reaction Analysis of Interlayer Seismic Isolation Structure

Interlayer seismic isolation is a new idea of isolation structure design.The isolation layer is set between the column and the floor to control the structure's earthquake reaction.Here the application of the interlayer seismic isolation in some engineering is introduced,and the finite element program—ETABS is used for making out the dynamic nonlinear time-history analysis.It is shown that the interlayer seismic isolation can effectively reduce the earthquake responses of structures and the deformation of isolation layer may be limited within the range of safety.
