(蘇州設(shè)計(jì)研究院股份有限公司， 蘇州 215021)［摘要］對(duì)張家港雙子樓酒店式公寓塔樓進(jìn)行動(dòng)力彈塑性分析，以了解結(jié)構(gòu)在罕遇地震作用下的彈塑性行為，檢驗(yàn)其結(jié)構(gòu)布置的合理性和結(jié)構(gòu)的抗震性能，研究構(gòu)件的損傷及屈服情況，找出結(jié)構(gòu)的薄弱部位及薄弱構(gòu)件以指導(dǎo)結(jié)構(gòu)設(shè)計(jì)。本工程酒店式公寓塔樓采用帶加強(qiáng)層的型鋼混凝土框架鋼筋混凝土核心筒混合結(jié)構(gòu)，該種體系在施工中往往采用核心筒領(lǐng)先外圍型鋼混凝土框架施工、伸臂桁架腹桿后裝的施工方案。為了確定該種施工次序?qū)ωQ向構(gòu)件的內(nèi)力及變形的影響，通過(guò)ETABS軟件進(jìn)行了專門的施工模擬分析，分析表明，該種施工次序?qū)ωQ向構(gòu)件的內(nèi)力及變形均有較大的影響，設(shè)計(jì)時(shí)應(yīng)予以考慮。［關(guān)鍵詞］超高層； 罕遇地震； 動(dòng)力彈塑性分析； 施工模擬分析中圖分類號(hào)：TU973.1+4，TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)20-0084-05Elasto-plastic time-history analysis and construction simulation analysis of serviced apartments twin towers in ZhangjiagangShen Yinliang, Wang Kaihua, Dai Yaping, Zhang Min（Suzhou Institute of Architectural Design Co.,Ltd., Suzhou 215021, China）Abstract: Elastic-plastic time-history analysis of serviced apartments twin towers in Zhangjiagang was performed to study the elastic-plastic behavior under the rare earthquake, to study the reasonable arrangements of the structure components as well as seismic performance, to study damage and yield conditions of components and to find out weak parts or components to strengthen. The twin towers adopts hybrid structural system of SRC column frame and core wall with strengthened layers. In construction of this structural system, core wall was usually constructed in advance compared to SRC column frame and installation of web members lags behind. In order to determine the effects of construction sequence on the internal forces and deformation on vertical components, ETABS software was used in construction simulation analysis. Analysis shows that construction sequence has great effects on the internal forces and deformation on vertical components, which should be considered in design.Keywords: super-tall building; rare earthquake; elastic-plastic time-history analysis; construction simulation analysis作者簡(jiǎn)介：沈銀良，碩士，工程師，Email:yinliang.shen@siad-c.com。參考文獻(xiàn)［1］戴雅萍，張敏，王開(kāi)華，等. 張家港雙子樓酒店式公寓塔樓結(jié)構(gòu)設(shè)計(jì)研究［J］. 建筑結(jié)構(gòu)，2013,43（20）：76-83.［2］JGJ 3—2010高層建筑混凝土結(jié)構(gòu)技術(shù)規(guī)程［S］. 北京：中國(guó)建筑工業(yè)出版社，2011.［3］ 北京MIDAS公司．MIDAS理論手冊(cè)［M］．2004.［4］ 北京邁達(dá)斯技術(shù)有限公司.
