摘要
为了研究层间隔震结构的减震效果和变化规律,通过运用SAP2000大型有限元分析软件,在建立层间隔震结构的三维模型基础上,设置所在不同的隔震层位置,对所建隔震结构模型进行仿真分析。输入选定的不同地震波,通过结构模型进行分析对比,得出层间隔震结构的变化规律和减震效果,同时讨论不同位置的隔震层对结构变化规律和减震效果的影响,从而验证层间隔震的有效性。
In order to study the layer damping effect and the change rule of interval structure By using the large finite element analysis software SAP2000,base on three-dimensional model of interlayer seismic structure,set the location of different isolation layer,simulation analysis was carried out on the model of isolation structures. Input different seismic wave which was selected,through the comparative analysis of the structural model,obtained interlayer seismic structure variation and damping effect,discuss effects of structural changes and damping effect of isolation layer in different position to verify the validity of interlayer seismic.
