摘　　要：近年来,为满足大型文化展演及体育赛事的举办需求,大型体育场馆的建设逐渐增多,具有大跨度、长悬挑等特点的体育场罩棚为结构设计带来了新的难点。文章以某体育场工程为背景,对采用悬挑空间管桁架结构体系的体育场钢罩棚开展受力性能分析,重点介绍了罩棚的建筑造型特点及结构布置形式,利用多种软件对结构进行静力分析、模态分析和考虑双非线性的屈曲分析,并对结构中的关键节点进行了精细化有限元分析。结果表明,结构主次桁架及支撑布置合理,各项性能指标均满足规范要求。文章对此类结构提出的相关设计建议可供同类工程参考。In recent years,in order to meet the needs of large-scale cultural performances and sporting events,the construction of large-scale stadiums and gymnasiums has gradually increased.The stadium canopy with the characteristics of large span and long cantilever has brought new difficulties to the structural design.Based on a stadium project,the analysis of the mechanical behavior on the steel canopy of the stadium with the cantilever spatial tube truss structure system were carried out.The architectural modeling features and structural layout of the canopy were mainly introduced in this paper.Static analysis,modal analysis and buckling analysis considering double nonlinearity were carried out by using a variety of software,and fine finite element analysis on the key nodes in the structure was carried out.The results show that the primary and secondary trusses and braces of the structure are arranged reasonably,and all performance indexes meet the requirements of standards.The relevant design suggestions for such structures put forward in this paper can be used as a reference for similar projects.
