【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。更多还原

【Abstract】 The dynamic time-history analysis method is adopted to design a kindergarten with base isolation in Xiamen.And then it analyzes the structure response in fortification earthquake and seldom-occurred earthquake under fortification intensity.Then the period,interlaminar shear and interlaminar displacement of the seismic structure and isolated structure are compared.The results show that,compared to the seismic structure,the period of isolated structure becomes longer,and the response of earthquake has been significantly reduced.Upper structure horizontal damping factor is 0.39.After designcheck,Structure isolation design meet current seismic design specification,the design offers reference for Similar engineering applications.更多还原
