[摘要]上海国际金融中心由3栋塔楼和1座巨型廊桥组成。3栋塔楼均为超高层建筑,结构高度分别为210,190,147m,塔楼均采用钢管混凝土框架-双核心筒-巨型支撑结构体系。系统介绍了整个项目结构设计的情况,并对结构设计的特点和难点进行了阐述,对特殊及关键的结构部位进行了计算和分析,如巨型支撑构件、巨型支撑与核心筒连接的节点、拉索幕墙对主体结构的影响等。分析结果表明,塔楼结构的双核心筒之间虽有大量楼板缺失,但通过巨型支撑的连接,结构具有较好的整体性。

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
