摘　　要：简述天津商业大学新建体育馆项目的工程概况,结合建筑造型和功能要求,提出单层网壳、环桁架单层网壳和环桁架拱支单层网壳三种结构方案,用MIDAS/Gen对三个方案进行建模分析并从杆件内力、结构变形、抗震性能、稳定承载力和经济性等方面进行对比,结果表明环桁架拱支单层网壳结构体系刚度分布合理、用钢量适中、反力分布较为均匀,为推荐选用的结构方案。The general situation of the new gymnasium of Tianjin University of Commerce is briefly introduced.Considering the architectural shape and function,three structural schemes,including single-layer lattice shell,single-layer lattice shell with loop truss and arch-supported single-layer lattice shell with loop truss,are put forward. Using MIDAS / Gen,the modeling and calculation are made respectively for each schemes,and the internal force of member,structural deformation,seismic performance,stable capacity and economic are compared. The result shows that the arch-supported single-layer lattice shell with loop truss is the recommend scheme because of the proper structural stiffness,moderate steel consumption and the uniform reaction force.
