张敏，宋鸿誉，张杜（苏州设计研究院股份有限公司， 苏州 215021）［摘要］扬州体育公园体育馆屋盖钢结构为大跨空间管桁架结构。除对屋盖钢结构进行单体模型计算分析外，还对考虑下部混凝土结构的整体模型进行计算分析，结合实际卸载情况进行施工卸载分析。由于比赛馆节点杆件交汇多，受力复杂，特别对转换桁架下弦节点进行了有限元分析及三组足尺节点试验，采取相应加强措施确保节点安全。［关键词］扬州体育公园； 四锥台形空间管桁架结构； 转换桁架； 卸载分析； 节点试验中图分类号：TU393.3 文献标识码：A 文章编号：1002-848X(2013)20-0006-05Structure design on steel roof of stadium in Yangzhou Sports ParkZhang Min, Song Hongyu, Zhang Du(Suzhou Institute of Architectural Design Co., Ltd., Suzhou 215021, China)Abstract: The steel roof of stadium in Yangzhou Sports Park is a large-span spatial tube truss structure. The model of steel roof structure was calculated independently while the whole model with lower concrete structure was analyzed considering construction unloading. The nodes of steel roof are formed by many members and have complicated loading conditions. Lower chord nodes of conversion truss were analyzed by finite element method and three groups of full-size nodes tests. Measures were taken to ensure the safety of nodes.Keywords: Yangzhou Sports Park; four cone-shaped spatial tube truss structure; conversion truss; unloading analysis; node test作者简介：张敏，教授级高级工程师，一级注册结构工程师，副总工程师，Email:min.zhang@siad-c.com。参考文献［1］GB 50017—2003 钢结构设计规范［S］. 北京:中国计划出版社，2003.［2］东南大学土木工程学院. 扬州体育馆钢结构节点试验报告［R］. 2005.
