摘要
采用弹塑性时程分析方法研究某16层隔震建筑的抗震性能,结果表明,一般抗震结构主要控制层间位移,上部结构的地震加速度远大于隔震结构.普通抗震结构在8度多遇及罕遇地震作用下已经进入了塑性阶段,部分区域已经破坏,而隔震结构在8度多遇及罕遇地震作用下仍处于弹性阶段,减少了震后维修.根据加速度响应得出隔震结构是一种有效的抗震措施.
The paper studied elastic-plastic time history analysis Seismic isolation performance of a 16-story building,the results show that general seismic structure of the main control layer displacement,seismic acceleration generally much larger than the upper structure of isolated structure.Ordinary seismic structure and in the case of 8degrees more rare earthquake has entered the plastic stage action,part of the region shall be subject to damage.The isolated structure in the case of 8degrees and more rare earthquake either in elastic phase,reducing maintenance after the earthquake structure.Isolated structural acceleration response is significantly less than conventional construction,the use of isolation structure is an effective seismic measures.
