(廣州瀚華建筑設(shè)計有限公司,廣州 510655)[摘要]采用基于性能的抗震設(shè)計方法,應(yīng)用SATWE,ETABS,MIDAS/Gen,ABAQUS6.5等軟件對一棟高度約265m超B級高度的超限高層建筑進行抗震超限分析,介紹了該結(jié)構(gòu)超限抗震設(shè)計情況和技術(shù)措施。[關(guān)鍵詞]超高層;小震;中震;大震;抗震性能目標;Pushover;彈塑性分析中圖分類號:TU973.17, TU973.212文獻標識碼:A文章編號:1002-848X(2011)08-0029-05Seismic design of Guangsheng International Building beyond code limitsYan Shiji, Yao Yongge, Zheng Jiandong(Guangzhou Hanhua Architects+Engineers Ltd., Guangzhou 510655, China)Abstract:Based on the performance-based seismic design method, seismic analysis of Guangsheng International Building with 265m-high was carried out by-SATWE,ETABS,MIDAS/Gen and ABAQUS6.5 softwares. The seismic design method and the technical measures of this-structure were introduced to give a reference to similar projects.Keywords:super high\|rise building;minor earthquakes;moderate earthquakes;major earthquakes;performance\|based seismic design goals;Pushover;elasto\|plastic time\|history analysis作者簡介:嚴仕基,高級工程師,Email:Yanshiji@gzhanhua.com。參考文獻[1]廣東省實施《高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程》(JGJ3—2002)補充規(guī)定[S]. 北京:中國建筑工業(yè)出版社,2005.[2]JGJ3—2002 高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程[S]. 北京:中國建筑工業(yè)出版社, 2002.
