蔣金梁,任牮時(浙江大學(xué)建筑設(shè)計研究院, 杭州 310027)[摘要]隔震結(jié)構(gòu)設(shè)計屬于結(jié)構(gòu)性能設(shè)計范疇,通過合理設(shè)計隔震層,減少上部結(jié)構(gòu)地震作用,以達到預(yù)期設(shè)計要求。結(jié)合工程實例,選用橡膠(鉛芯)隔震支座作為隔震裝置,采用簡化方法和時程分析方法分析其隔震性能,重點分析了隔震結(jié)構(gòu)減震效果和隔震層位移,均能滿足規(guī)范要求。[關(guān)鍵詞]體育館;隔震結(jié)構(gòu);隔震支座;簡化方法;時程分析法中圖分類號:TU375.4 文獻標(biāo)識碼:A 文章編號:1002-848X(2013)01-0014-03Design and application of isolation structure on a gymnasiumJiang Jinliang, Ren Jianshi(Architectural Design and Research Institute of Zhejiang University, Hangzhou 310027, China)Abstract: The design of isolation belongs to the performance-based seismic design. The rational isolation layer is required to decrease the seismic action, in order to achieve the expected design requirement. Based on an engineering project, the lead rubber bearing was applied to the seismic isolator.The simplified method and time history analysis were applied to analyze the isolation performance, including the damped effect and isolation layer displacement.The design reveals that they can meet code requirements.Keywords: gymnasium; isolation structure; isolation bearing; simplified method; time history analysis作者簡介:蔣金梁,碩士,高級工程師,Email:hzjiangjinl@163.com參考文獻[1]GB 50011-2001建筑抗震設(shè)計規(guī)范[S]. 2008年版. 北京:中國建筑工業(yè)出版社,2008.[2]黨育,杜永峰,李慧.基礎(chǔ)隔震結(jié)構(gòu)設(shè)計及施工指南[M]. 北京:中國水利水電出版社,2007.[3]孫相峰,潘文.疊層橡膠墊基礎(chǔ)隔震建筑結(jié)構(gòu)設(shè)計方法與應(yīng)用[J].世界地震工程,2007,23(4):39-42.[4]孫相峰,潘文.多層隔震結(jié)構(gòu)兩階段設(shè)計方法[J].世界地震工程,2008,24(3):25-28.
