（悉地國際設(shè)計(jì)顧問（深圳）有限公司, 深圳 518057）［摘要］采用框架-核心筒結(jié)構(gòu)體系的福州升龍環(huán)球大廈屬于超B級(jí)高度的超高層建筑。針對(duì)框架-核心筒結(jié)構(gòu)的震害情況，從概念設(shè)計(jì)出發(fā)，加強(qiáng)了抗震構(gòu)造措施并調(diào)整結(jié)構(gòu)構(gòu)件的內(nèi)力以滿足多道防線的設(shè)計(jì)要求。采用多套軟件對(duì)結(jié)構(gòu)在多遇地震下的響應(yīng)進(jìn)行了復(fù)核計(jì)算，并對(duì)關(guān)鍵構(gòu)件的抗震性能目標(biāo)進(jìn)行了驗(yàn)算。罕遇地震下結(jié)構(gòu)的動(dòng)力彈塑性分析結(jié)果表明，層間位移角小于1/100，滿足大震不倒的要求。［關(guān)鍵詞］超高層建筑; 框架-核心筒結(jié); 概念設(shè)計(jì); 抗震設(shè)計(jì)中圖分類號(hào)：TU973.31 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2014)19-0052-05Seismic design of Fuzhou Shenglong Worldwide TowerHe Yuanming, Peng Zhaocai, Liu Chang, Huang Yongjun（CCDI International（Shenzhen）Design Consultants Co., Ltd., Shenzhen 518057, China）Abstract: Fuzhou Shenglong Worldwide Tower, which is frame-tube structure, belongs to the super high-rise building of exceeding B level height. Based on the conceptual design, the seismic construction were enhanced and seismic internal force of structure components was adjusted to meet the needs of multi-line defense against the earthquake damage of frame-tube structure. Seismic response of the structure was calculated by some softwares and the seismic performance objectives of key components were checked. The dynamic elastic-plastic results of the structure under rare earthquake show that the maximum value of story displacement drifts is less than 1/100 and the structure will not collapse under rare earthquake.Keywords: super high-rise building; frame-tube structure; conceptual design; seismic design作者簡(jiǎn)介：何遠(yuǎn)明，碩士，工程師，Email: heyuanming237@sina.com。參考文獻(xiàn)［1］ＪＧＪ３—2010 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，2011．［２］ＧＢ50011—2010建筑抗震設(shè)計(jì)規(guī)范［Ｓ］．北京：中國建筑工業(yè)出版社，2010．［３］ＧＢ50223—2008建筑工程抗震設(shè)防分類標(biāo)準(zhǔn)［Ｓ］．北京：中國建筑工業(yè)出版社，2008．［４］福州市升龍環(huán)球大廈超高層建筑工程場(chǎng)地地震安全性評(píng)價(jià)報(bào)告［R］.福州：福建地震地質(zhì)工程勘察院，2012.［５］徐培福,傅學(xué)怡,王翠坤，等.復(fù)雜高層建筑結(jié)構(gòu)設(shè)計(jì)［M］.北京：中國建筑工業(yè)出版社,2005: 396-398．［６］徐培福,薛彥濤,肖從真，等.帶轉(zhuǎn)換層型鋼混凝土框架-核心筒結(jié)構(gòu)模型擬靜力試驗(yàn)對(duì)抗震設(shè)計(jì)的啟示［J］.土木工程學(xué)報(bào), 2005, 38(9): 1-8.
