摘　　要：对厦门某一幼儿园教学楼进行基础隔震设计,采用动力时程分析方法,分析结构在设防烈度下中震及大震作用下的结构响应。对比抗震结构和隔震结构两者的周期、层间剪力和层间位移,对比结果表明,相较于抗震结构,隔震结构的周期变长,隔震结构受到的地震作用效应大幅降低,上部结构的水平向减震系数为0.39。经设计验算,结构隔震设计满足我国现行建筑抗震设计规范的规定,可为类似基础隔震工程的应用提供借鉴。The dynamic time -history analysis method is adopted to design a kindergarten with base isolation in Xiamen. And then it analyzes the structure re- sponse in fortification earthquake and seldom - occurred earthquake under fortification intensity. Then the period, interlaminar shear and interlaminar displace- ment of the seismic structure and isolated structure are compared. The results show that, compared to the seismic structure , the period of isolated structure be- comes longer, and the response of earthquake has been significantly reduced. Upper structure horizontal damping factor is 0.39. After designcheek, Structure isolation design meet current seismic design specification , the design offers reference for Similar engineering applications .
