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。
Shanghai International Financial Center consists of 3 towers and 1 giant corridor bridge. All three towers are super high-rise buildings with structures of 210,190 and 147m in height, respectively. All of the towers are made of CFST framework - dual-core tube-giant support structure. The whole project structure design was introduced. The characteristics and difficulties of the structure design were described. The special and key structural parts were calculated and analyzed. For example, the giant support members, the joints between the giant supports and the core tube, Cable curtain wall on the main structure and so on. The analysis results show that although there are a large number of floors missing between the two core cylinders of the tower structure, the structure has good integrity through the connection of the giant support.
