（中國建筑設(shè)計(jì)研究院，北京 100044）[摘要] 針對某超限大跨鋼結(jié)構(gòu)屋蓋的結(jié)構(gòu)形式，明確所采用的結(jié)構(gòu)安全控制荷載和控制目標(biāo)。通過計(jì)算分析及概念設(shè)計(jì)找出結(jié)構(gòu)關(guān)鍵桿件和薄弱部位，通過計(jì)算及抗震措施進(jìn)行加強(qiáng)，確保整個(gè)大跨結(jié)構(gòu)的抗震安全。[關(guān)鍵詞] 超限大跨結(jié)構(gòu);鋼結(jié)構(gòu);概念設(shè)計(jì)中圖分類號：TU973.3 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2013)S1-0290-05Structural design of Wanzhou StadiumLiu Songhua，You Tianzhi，Bi Lei，Zhou Xin，He Yu(China Architecture Design & Research Group,Abstract: According to the structure type of an out-of-codes large-span steel roof structure, the control load and control objectives for structure safety are determined. Computational analysis and conceptual design have been taken to find the key member and weakness part of the structure, and also some seismic strengthening measures have been taken to insure the seismic safety of the large-span structure.Keywords: out-of-codes large-span structure; steel structure; conceptual design
