（中国建筑设计研究院，北京 100044）[摘要] 针对某超限大跨钢结构屋盖的结构形式，明确所采用的结构安全控制荷载和控制目标。通过计算分析及概念设计找出结构关键杆件和薄弱部位，通过计算及抗震措施进行加强，确保整个大跨结构的抗震安全。[关键词] 超限大跨结构;钢结构;概念设计中图分类号：TU973.3 文献标识码：A 文章编号：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
