［摘要］西双版纳傣秀剧场屋盖造型新颖，分为上下两层，根据建筑特点，其结构分为内屋盖、上挑檐、下挑檐三部分。根据结构体系及其特点，对结构进行了合理的设计，并介绍了本工程的风洞试验和风振分析结果。采用SAP2000软件进行了结构线性分析和截面设计，利用ANSYS软件对屋盖挠度、结构稳定性和节点应力进行了分析。结果表明，各项指标均满足要求。［关键词］西双版纳傣秀剧场; 大跨度钢结构; 挑檐结构; 节点分析中图分类号：TU318，TU391 文献标识码：A 文章编号：1002-848X(2015)20-0018-04
Structural design of the steel roof for Dai Show Theater in XishuangbannaZu Yizhen, Wang Wenyuan, Zhang Tongyi, Wang Xiao, Jiang Xiaolin, Shu Tianming(China IPPR International Engineering Co., Ltd., Beijing 100089, China)Abstract: With the roof of novel shape, Dai Show Theater in Xishuangbanna is divided into two layers of upper layer and lower layer. According to the architecture characteristics, the structure is divided into three parts of the inner roof, upper cornice and lower cornice. According to the structural system and its characteristics, the structure was designed reasonably, and the wind tunnel test and wind vibration analysis results of this project were introduced. SAP2000 software was used to carry out linear analysis and cross-section design. The ANSYS software was used to analyze the roof deflection, the structural stability and stress of the joint. The results indicate that all the indexes meet the specified requirements.Keywords: Dai Show Theater in Xishuangbanna; large-span steel structure; roof overhang structure; joint analysis作者简介：祖义祯，博士，高级工程师，Email：zuyizhen@ippr.net。
