【摘要】 某商住楼位于地震高烈度区江苏省濉宁县,为了提高其抗震性能采用了基础隔震技术,采用时程分析法对隔震结构的地震反应进行了设计。分析表明,隔震结构在大震作用下仍处于弹性工作状态,隔震层在罕遇地震下工作状态稳定,上部结构的地震响应有了明显的降低,结构由传统抗震设计的"大震不倒"提高到了"大震不坏",具有优越的抗震性能。更多还原

【Abstract】 The design method of hybrid base isolation was applied to a lowest-frame masonry building in Suining of Jiangsu Province,which is a region of high earthquake intensity.The behavior of the isolated building under earthquakes was studied with time history analysis method.Analysis results prove the stabilized operating state of isolation floor,the obvious decreasing in seismic response of upper structure,as well as excellent aseismic behavior.更多还原
