［摘要］某超高層住宅建筑為68層，房屋高度為217.550m。通過(guò)對(duì)結(jié)構(gòu)經(jīng)濟(jì)性、凈使用面積、抗傾覆等分析，確定了該建筑的結(jié)構(gòu)體系采用框架-核心筒結(jié)構(gòu)。同時(shí)根據(jù)項(xiàng)目特點(diǎn)，通過(guò)對(duì)比不同類(lèi)型豎向構(gòu)件的經(jīng)濟(jì)性，選用了適合的豎向構(gòu)件形式，即局部樓層核心筒外墻采用鋼板或型鋼混凝土墻，框架柱采用鋼管混凝土疊合柱。針對(duì)建筑布置特殊性及規(guī)范限制，對(duì)核心筒外墻中部均勻布置型鋼、核心筒角部開(kāi)洞、鋼管混凝土疊合柱正截面承載力等關(guān)鍵技術(shù)做了詳細(xì)分析，保證了結(jié)構(gòu)在大震下的安全性能。

Abstract:A super high-rise residential building has 68 floors and the height of the building is 217.550m. Through the analysis of structural economy, net use area, and anti-overturning, it is determined that the structural system of the building adopts a frame-core tube structure. Meanwhile, by comparing the construction costs of different vertical members, a suitable vertical member form was selected, that is, steel plate or steel reinforced concrete wall is used as core tube exterior wall of the local floor, while steel tube reinforced concrete column is utilized for frame column. In view of the particularity of building layout and code restrictions, detailed analyses of key technologies such as the uniformly arranged section steel in the middle of the outer wall of the core tube, openings at the corner of the core tube, and the bearing capacity of the cross-section of the steel tube-reinforced concrete column were carried out, which ensures safety performance of the structure under rare earthquake. 

Keywords:super high-rise building； structural selection； key technology； frame-core tube structure； steel reinforced concrete wall； opening at the corner of core tube； steel tube-reinforced concrete column
