(中國(guó)電子工程設(shè)計(jì)院，北京 100840)［摘要］新長(zhǎng)江國(guó)際酒店采用型鋼混凝土外框架-鋼筋混凝土核心筒結(jié)構(gòu)體系，存在樓板局部不連續(xù)、樓層剛度突變、扭轉(zhuǎn)位移比較大等多項(xiàng)不規(guī)則，屬超限高層建筑。采用基于性能的抗震設(shè)計(jì)方法，經(jīng)試算，選取抗震性能目標(biāo)為C級(jí)。采用SATWE和ETABS軟件分別進(jìn)行了小震反應(yīng)譜分析和彈性時(shí)程分析，在此基礎(chǔ)上，又進(jìn)行了中震彈性分析和中震不屈服驗(yàn)算，并采用ABAQUS軟件對(duì)結(jié)構(gòu)進(jìn)行大震作用下的動(dòng)力彈塑性分析。計(jì)算結(jié)果表明，結(jié)構(gòu)各項(xiàng)控制性指標(biāo)均能滿足規(guī)范要求，抗震加強(qiáng)措施合理有效，結(jié)構(gòu)整體性能及構(gòu)件承載力均可達(dá)到預(yù)期的性能目標(biāo)。［關(guān)鍵詞］超限高層建筑; 反應(yīng)譜分析; 彈塑性分析; 基于性能的抗震設(shè)計(jì)中圖分類號(hào)：TU318 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2014)23-0059-06Performance-based seismic design on Xinchangjiang International HotelLi Mingyu, Su Yunpeng, Han Hejun, Wang Haiming, Xiao Jia(China Electronics Engineering Design Institute, Beijing 100840, China)Abstract: Xinchangjiang International Hotel, which adopts structural system of steel reinforced concrete frame and reinforced concrete core wall, is an out-of-code high-rise building with irregularities of discontinuous floor in local parts, abruptness of story lateral rigidity and large torsion-displacement ratio. The performance-based seismic design method was used in structural design and the seismic performance goal was set as level C. Response spectrum analysis and elastic time-history analysis under the frequent earthquake were carried out by SATWE and ETABS software, and the elastic analysis and non-yielding check under the fortification earthquake were also carried out. The dynamic elasto-plastic analysis of the structure under the rare earthquake was carried out by ABAQUS software. The results show that all controlling indicators of the structure can satisfy requirements of the code. The seismic strengthening measures are rational and effective, and the overall performance of the structure and bearing capacity of the member can achieve the expected performance goals.Keywords: out-of-code high-rise building; response spectrum analysis; elasto-plastic analysis; performance-based seismic design作者簡(jiǎn)介：李明雨，碩士，一級(jí)注冊(cè)結(jié)構(gòu)工程師，Email：limingyu@ceedi.cn。參考文獻(xiàn)［1］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.［2］江陰新長(zhǎng)江雅閣大酒店工程場(chǎng)地地震安全性評(píng)價(jià)報(bào)告［R］. 無(wú)錫: 無(wú)錫市地震工程檢測(cè)中心, 2010.［3］GB 50011—2010 建筑抗震設(shè)計(jì)規(guī)范［S］. 北京: 中國(guó)建筑工業(yè)出版社, 2010.［4］何偉明，劉鵬，殷超，等. 北京財(cái)富中心二期辦公樓超高層結(jié)構(gòu)體系設(shè)計(jì)研究［J］. 建筑結(jié)構(gòu), 2009, 39(11): 1-8.［5］江陰新長(zhǎng)江國(guó)際酒店結(jié)構(gòu)抗震設(shè)防專項(xiàng)審查報(bào)告［R］. 北京：中國(guó)電子工程設(shè)計(jì)院, 2012.
