（奧雅納工程顧問(wèn)，北京 100020）［摘要］北京國(guó)銳金嵿A，B座塔樓結(jié)構(gòu)高度為179.45m，采用型鋼混凝土柱鋼梁框架-鋼筋混凝土核心筒結(jié)構(gòu)體系。本塔樓的結(jié)構(gòu)特點(diǎn)為不設(shè)置伸臂桁架和腰桁架，平面形狀為矩形，縱向較窄，橫向柱網(wǎng)為大小跨。介紹了該結(jié)構(gòu)的結(jié)構(gòu)體系、彈性分析、靜力彈塑性分析和針對(duì)中震拉應(yīng)力進(jìn)行的方案改進(jìn)等內(nèi)容，結(jié)構(gòu)在較為經(jīng)濟(jì)的條件下滿足各項(xiàng)整體指標(biāo)及抗震性能目標(biāo)。［關(guān)鍵詞］高層建筑; 混合結(jié)構(gòu); 靜力彈塑性分析; 抗震性能化設(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)24-0054-05Structural design of Beijing Guorui Kingdom Tower A & BJonathan Kerry, Mai Huilin, Su Guozhu, Wu Tao, Yang Yang, Xu Zhaoyang(Arup, Beijing 100020, China)Abstract: Guorui Kingdom Tower A & B in Beijing has the structural height of 179.45m. Structural system of reinforced concrete core wall plus composite frame which consists of steel reinforced concrete column with steel beam is adopted in the tower. The characteristics of the tower structure are as follows: there is not any outrigger or belt truss; plane shape is rectangular with narrow width in the transverse direction; column grid in the longitudinal direction is uneven. The structural system of the tower was introduced as well as elastic analysis, pushover analysis and structural improvement to reduce tensile stress under the fortification earthquake.The structure provides a cost-effective solution that meets all global requirements and seismic performance criteria.Keywords: high-rise building; mixed structure; pushover analysis; performance-based seismic design作者簡(jiǎn)介：Jonathan Kerry，碩士，英國(guó)認(rèn)證工程師，英國(guó)土木工程師協(xié)會(huì)會(huì)員，Email: jonathan.kerry@arup.com。參考文獻(xiàn)［1］建質(zhì)［2010］109號(hào) 超限高層建筑工程抗震設(shè)防專項(xiàng)審查技術(shù)要點(diǎn)［S］.2010.［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］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.
