［摘要］上海國際金融中心由3棟塔樓和1座巨型廊橋組成。3棟塔樓均為超高層建筑，結(jié)構(gòu)高度分別為210，190，147m，塔樓均采用鋼管混凝土框架-雙核心筒-巨型支撐結(jié)構(gòu)體系。系統(tǒng)介紹了整個(gè)項(xiàng)目結(jié)構(gòu)設(shè)計(jì)的情況，并對結(jié)構(gòu)設(shè)計(jì)的特點(diǎn)和難點(diǎn)進(jìn)行了闡述，對特殊及關(guān)鍵的結(jié)構(gòu)部位進(jìn)行了計(jì)算和分析，如巨型支撐構(gòu)件、巨型支撐與核心筒連接的節(jié)點(diǎn)、拉索幕墻對主體結(jié)構(gòu)的影響等。分析結(jié)果表明，塔樓結(jié)構(gòu)的雙核心筒之間雖有大量樓板缺失，但通過巨型支撐的連接，結(jié)構(gòu)具有較好的整體性。

Abstract:Shanghai International Financial Center is composed of three towers and a huge bridge. The three towers are all super high-rise buildings with the structural height of 210，190，147m respectively. CFT frame-dual concrete core-huge brace structure system is adopted in the towers. The project structural summary, characteristics and difficulties were introduced. Calculation and analysis have been done in some special and important structural parts, such as huge brace members, connection between huge brace and concrete core, influence of the cable curtain wall on the main structure, and ect. The results show that there are a large number of slab gaps between the twin core walls of the tower structure, but the structure has good integrity through the connection of huge braces.
Keywords:super high-rise building； dual concrete core; huge brace; deep excavation
