［摘要］某辦公樓位于地震高烈度區(qū)江蘇省宿遷市，為了提高其抗震性能采用了基礎(chǔ)隔震技術(shù)。由于我國規(guī)范對地震高烈度區(qū)建造高層隔震建筑還沒有明確的設(shè)計(jì)依據(jù)，文中將基于性能的設(shè)計(jì)方法應(yīng)用于該建筑的基礎(chǔ)隔震設(shè)計(jì)中。為滿足設(shè)定的抗震性能目標(biāo)，隔震層采用了組合隔震形式，由純天然橡膠隔震支座、鉛芯橡膠隔震支座和粘滯阻尼器組成。分析表明，各類隔震器充分發(fā)揮了其設(shè)計(jì)性能，隔震層在罕遇地震下工作狀態(tài)穩(wěn)定，上部結(jié)構(gòu)的地震響應(yīng)有了明顯的降低。

Abstract:The design method of hybrid base isolation was applied to an office building in Suqian, which is a region of high earthquake intensity. In China, there is no specific design basis for isolated technique application in high-rise buildings. Performance-based seismic design method was applied to this building. In order to reach the setting target of seismic performance, combination form was adopted in isolation floor composed of rubber bearing and viscous damping. Analysis results prove the stabilized operating state of isolation floor, the obvious decreasing in seismic response of upper structure, as well as the satisfaction for the design requirements.
Keywords:high-rise building; base isolation; performance-based design method; hybrid isolation
