摘要
对某12层的框架剪力墙结构工程实例进行了隔震设计计算分析。利用ETABS模型运用时程分析法对隔震结构进行了计算,由结果分析可知,隔震装置在多遇地震作用下能够延长结构的周期、减小结构的层间位移角,有效地减小结构的地震反应;在罕遇地震作用下楼层层间位移角能满足大震不倒的要求,隔震支座的位移和轴力均能满足现行抗震设计规范要求。
In this paper,a tall building project of seismic isolation design is calculated and analyzed.It is a frame-shear wall structure,which has twelve stories on the ground.And then,the time history analysis method is used to calculate the isolation structure.It is found that isolation equipment can extend the period of the structure and reduce the story drift in frequency earthquake.And it also can control the response of the structure.In rare earthquake,the story drift can meet the demand of uncollapse,the displacement and force of the equipment can satisfy the demand of the code for seismic design of building.
