摘要
采用有限元软件,对某高层隔震结构进行了动力弹塑性时程分析,上部结构采用弹塑性质点系模型,隔震层考虑每个橡胶支座的水平和竖向的非线性动力特性,计算出了隔震结构在不同设防烈度下的位移、加速度、层间剪力等地震反应,并总结出了一些有益的规律。
A high-level Isolation structure is calculated by using the methods of the power-plastic time-history analysis.Elastic-plastic model of particle system is used for the upper structure and each of the rubber bearing on the level and the vertical nonlinear dynamic properties is considered.Displacement,acceleration and shear in Isolation layer between the earthquake response are calculated.Some of the law is summed up at last.
