摘　　要：基于某高校体育馆钢结构屋盖设计过程,比选了3种不同屋盖结构体系,最终选择空间倒三角钢桁架结构作为本项目的屋盖结构形式。采用有限元软件SAP2000对钢结构屋盖进行整体建模,对结构整体动力特性、整体抗震、位移、各杆件设计强度(弯曲、抗剪)、整体稳定应力、重要节点进行有限元分析,经计算分析该项目主馆屋盖钢结构的各项性能均满足规范要求,可保证结构受力的安全可靠。The design process of the steel structure roof of a university gymnasium was introduced,and three different roof structure systems were compared and selected,and finally the spatial inverted triangular steel truss structure was selected as the roof structure form of this project.The finite element software SAP2000 was used to model the steel structure roof as a whole,and the finite element analysis was carried out on the overall dynamic characteristics of the structure,overall seismic resistance,displacement,design strength of each member(bending,shear),overall stability stress,and important nodes.After calculation and analysis,the performance of the steel roof structure of the main building meets the requirements of the specification to ensure the safety and reliability of the structure.
