（同济大学建筑设计研究院（集团）有限公司, 上海 200092）［摘要］上海中心大厦的幕墙系统采用了独特的双层幕墙系统，其中内幕墙沿楼面边缘呈圆柱式布置，外幕墙平面呈圆角三角形，且呈现扭转收缩上升的几何形态，远离主体结构悬挂在上下两道加强层之间。由于外幕墙体量巨大、几何形态不规则，且采用柔性的支撑结构体系，给外幕墙的分析、设计、建造带来许多前所未有的技术挑战。对上海中心柔性悬挂式幕墙系统的建筑设计理念、几何形态、幕墙的风荷载研究、支撑结构体系选型及幕墙节点设计进行了介绍，可为类似工程提供有益的借鉴和参考。［关键词］上海中心大厦; 幕墙; 悬挂式幕墙; 双层幕墙; 幕墙支撑结构中图分类号：TU318，TU973 文献标识码：A 文章编号：1002-848X(2013)24-0001-05Design of innovative flexible suspend curtain wall system of Shanghai TowerDing Jiemin, He Zhijun, Li Jiupeng（Architectural Design & Research Institute of Tongji University (Group) Co., Ltd., Shanghai 200092, China）Abstract: Shanghai Tower has a unique design with an inner and outer “double-skin” curtain wall system. An interior curtain wall layouts along the edge of the typical circular floor slabs. An outer exterior curtain wall is a triangular slightly convex shape in plan with rounded corners. The outer exterior curtain wall is suspend between the upper and lower two strengthened story, twists and tapers from bottom to top. Because its characteristics of large scales, complex geometry and using flexible support system, a number of challenge for the analysis, design and construction of exterior curtain wall was created. The idea of architectural design, geometry, study of wind load, structural form selection and design of connection, of flexible suspend curtain wall system of Shanghai Tower were introduced, which could be useful reference for similar project.Keywords: Shanghai Tower; curtain wall; suspend curtain wall; double-skin curtain wall; curtain wall support structure*上海市科技攻关计划项目(09dz1207704）。作者简介：丁洁民，教授，博士生导师，Email:Djm@tjadri.com。参考文献［1］丁洁民，何志军. 上海中心大厦柔性悬挂式幕墙支撑结构分析与设计［J］. 建筑结构, 2013，43(9): 5-9.［2］DING J M, LI J P, HE Z J, et al.
