| 摘 要： | 大底盘塔结构竖向刚度分布不均匀，在地震作用下会导致破坏。在刚度突变处设置隔震层，运用有限元软件SAP2000对结构进行反应谱分析，对比隔震结构与非隔震结构在位移、周期、剪力等方面的变化情况，评判隔震效果，并由此得出一些有参考意义的结论。

| Abstract: | The tower structure with large podium that has non-uniform distributed vertical stiffness can cause destroy under the earthquake excitation. An isolation floor is inserted at the zone where the stiffness of the structure is changed sharply. The finite element software SAP 2000 is used to analyze the response spectrum of the structure. The displacement, period and shear force etc. for the structures with and with no isolated floor are compared to estimate the isolate effects. Some useful conclusions are obtained at the end of the paper. |
