某文体中心管桁架结构设计研究

Research and analysis on pipe truss structure of one sport center

某文体中心屋盖采用空间钢管桁架结构,桁架最大跨度53.0m,最大悬挑18.0m。采用3D3S计算软件对结构在各主要荷载组合工况下进行受力分析。结果表明:结构受力合理,构件强度、稳定及变形均满足规范要求,并满足建筑造型及使用功能要求,为该类工程的结构设计提供参考。

The spatial steel pipe truss structure is used in a sport center roof. The largest span is 53. 0m and the largest cantilever is 18. 0m. Using 3D3 S software,the structure stress analysis was carried out under the working condition of the main load combination. The results show that the structure is reasonable,the strength,stability and deformation can satisfy the requirements of specification and the requirement of building shape and function,which provides reference for similar engineering design.
