摘　　要：为了研究基于经济性能下大跨钢结构体系方案的优选,以西安某高校的体育训练馆工程为背景,根据设计造型先初选两种结构方案,应用SAP2000有限元软件分别建立两种方案的单榀模型及整体模型,对其进行分析计算和优化设计.通过对两种方案在受力性能、用钢量、施工工艺等方面的对比,确定设计采用的最佳经济方案.最后,通过对现场静载试验结果的分析,验证了文中有限元模型建立的正确性和方案选择所采用数据的可靠性,提出了较为可行的结构体系方案优选的方法,为该类结构的设计选型提供了较有力的依据.For a research on the select ition of optimum scheme based on economical performance, a gymnasium on a campus in Xi＇an is taken as example. According to design model, two types of schemes are roughly selected. The single model and entire model of two schemes is established by the finite element software SAP2000 . The final design project is determined by contrasting the two schemes＇ mechanical performance, steel level and construction technology. Comparison of the scene static test and theoretical analysis, its calculated results accorded well with those from the test data. The results of calculation showed that the model is correct and scheme selection is reliable. The method of optimum scheme selection is put forward and the evidence of similar structural scheme selection is supplied in this article.
