(深圳大学建筑设计研究院,深圳 518060)[摘要]深圳坪山体育馆屋顶采用新颖的弦支穹顶结构体系。弦支穹顶是一种刚柔杂交的预应力钢结构体系,实际工程应用较少,施工经验不足,因此针对此结构施工全过程的计算模拟分析显得十分重要。结合工程特点,充分考虑施工实际条件,选定施工方案和施工张拉顺序,对预应力张拉整体结构施工全过程进行有限元模拟计算,分析了预应力张拉过程中结构的变形、内力变化规律,确保了张拉施工过程中结构的安全。[关键词]单层网壳;弦支穹顶;索杆体系;张拉施工;全过程施工模拟中图分类号:TU318,TU375文献标识码:A文章编号:1002-848X(2011)04-002904Construction and process simulation analysis for suspend-dome structure of Pingshan Basketball Gymnasium for Universidad 2011 ShenzhenWu Bing, Meng Meili, Fu Xueyi(The Institute of Architecture Design & Research, Shenzhen University, Shenzhen 518060, China)Abstract:Suspend-dome structure is adopted in Pingshan Basketball Gymnasium for Universidad 2011 Shenzhen. The suspend-dome is a prestressed structural system with the combination of rigid-flexible. Due to the less of actual projects and the lack of construction experience, the analysis of the whole construction simulation for the roof would be much important. Focused on the features of the project, considering the actual condition of the constrution, the constuction plan and the tension sequence were chosen, and the prestressed construction simulation analysis was carried out through finite element calculation.The laws of member force and deformation evolution were achieved from the analysis, which would be used to make sure the safty of the construction process.Keywords:sing-layer reticulated dome; suspend-dome structure; cable-bar structure system; tension construction; the whole construction simulation*国家自然科学基金(50248005),国家自然科学基金(50578096),深圳大学建筑设计研究院科学发展基金项目(2009001)。作者简介:吴兵, 硕士,高级工程师,Email: wufpy@yahoo.com.cn。参考文献[1]孟美莉,吴兵,傅学怡,等.第26届世界大学生运动会篮球馆弦支穹顶屋盖结构设计[J].建筑结构,2011,41(4):24\|28,10[2]吴兵,孟美莉,傅学怡,等.2011年第26届世界大学生运动会篮球馆结构设计[J]. 建筑结构,2009,39(S1):34-41.[3]傅学怡,曹禾,张志宏,等.济南奥体中心体育馆整体结构分析[J]. 空间结构,2008,14(4):3-7.[4]张国军,葛家琪,秦杰,等.2008年奥运会羽毛球馆弦支穹顶预应力张拉模拟施工过程分析研究[J]. 建筑结构学报,2007,28(6):31-38.[5]郭正兴,王永泉,罗斌,等.济南奥体中心体育馆大跨度弦支穹顶预应力拉索施工[J]. 施工技术,2008,37(5):133-135.
