［摘要］苏州文博中心项目包含吴江博览中心（南区）和苏州大剧院（北区）两大建筑，两建筑造型新颖独特，建筑使用功能要求繁多，且建筑空间关系相对复杂。高、低位两条飘带更是本项目亮点，其体型复杂，为扭曲的空间桁架结构，通过变换角度最终与南北区两栋建筑连为一体。对飘带进行了风荷载、温度作用、地震作用分析，提出了飘带结构整体稳定及上人舒适度问题的解决方案，并简要介绍了飘带下部两大建筑的结构体系、超长悬挑的解决方案和一个新型桁架端部节点。［关键词］苏州文博中心; 飘带; 歌剧院; 博物馆; 风振; 空间桁架; 温度效应; 调谐质量阻尼器中图分类号：TU318 文献标识码：A 文章编号：1002-848X(2015)24-0086-06
Structural design of Suzhou Culture & Expo CenterKong Qiming, Zhao Junzhao, Lai Shaoping, Chris Townsend, Ding Jianhao, Zhu Ligang, Andrew Luong(Arup, Shanghai 200031, China)Abstract: The project of Suzhou Culture & Expo Center (SCEC) comprises two buildings of the Wujiang Museum & Exhibition Centre (South) and the Suzhou Opera House (North). Each building has a novel and unique shape with a variety of architectural functions and relatively complicated building spatial relationships. Two ribbon-shaped structures spanning over the buildings in high and low levels are highlights of the project. The ribbon-shaped structures, which adopt twisted space truss structure, have complex geometry which changes angles along the length to connect the North and South buildings with a single facade scheme. Wind load, temperature action, seismic analysis, overall stability and comfort solution of the ribbon-shaped structures were proposed, and structural systems of the two buildings under ribbon-shaped structures, long cantilever solution and a new truss end connection were briefly described.Keywords: Suzhou Culture & Expo Center; ribbon; opera; museum; wind vibration; space truss; temperature effect; tuned mass damper作者简介：孔启明，硕士，高级工程师，Email：Qi-ming.kong@arup.com。
