| 摘 要： | 采用SAP2000的结构分析软件,对某高层框架结构进行在多维地震波输入下的非线性时程分析.计算和比较的结果表明:高层建筑中采用基础隔震也能收到良好的效果,特别是绝对加速度反应将会大大降低;多维地震动作用下,完全对称、各层刚度相同的结构反应不一定会增大,带大底盘、各层刚度有变化的框架结构反应会增大;裙房对于高层建筑的隔震...

| Abstract: | A non-linear time-history analysis of a high-level isolation structure under multi-dimensional seism is done by using the SAP2000 structural analysis software.The results of calculation and comparison show that the good effects are received in high-level base-isolation structure,especially the absolute acceleration response is greatly reduced;under multi-dimensional seismic,the responses of the structure with full symmetry and the same stiffness in each layer,may not be increased;but for the structure with podium and different stiffness of each layer,the responses will be increased.The podium can make a positive affect to shock isolation system of high-level structure. |
