［摘要］西雙版納傣秀劇場屋蓋造型新穎，分為上下兩層，根據(jù)建筑特點，其結(jié)構(gòu)分為內(nèi)屋蓋、上挑檐、下挑檐三部分。根據(jù)結(jié)構(gòu)體系及其特點，對結(jié)構(gòu)進(jìn)行了合理的設(shè)計，并介紹了本工程的風(fēng)洞試驗和風(fēng)振分析結(jié)果。采用SAP2000軟件進(jìn)行了結(jié)構(gòu)線性分析和截面設(shè)計，利用ANSYS軟件對屋蓋撓度、結(jié)構(gòu)穩(wěn)定性和節(jié)點應(yīng)力進(jìn)行了分析。結(jié)果表明，各項指標(biāo)均滿足要求。［關(guān)鍵詞］西雙版納傣秀劇場; 大跨度鋼結(jié)構(gòu); 挑檐結(jié)構(gòu); 節(jié)點分析中圖分類號：TU318，TU391 文獻(xiàn)標(biāo)識碼：A 文章編號：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作者簡介：祖義禎，博士，高級工程師，Email：zuyizhen@ippr.net。
