摘　　要：结合某体育馆预应力索拱屋架方案的设计 ,研究了预应力索拱结构的优选和有限元分析方法 ,比较了不同布索方案和拱脚抗推刚度对预应力索拱结构内力和变形的影响 ,并提出了一些具体的设计建议。Combined with the design plan of the prestressed tightwire arch roof in a gymnasium,this paper studied the optimize choose form and the finite element analysis methods for the prestressed tightwire arch,compared the effects of force and displacement of the prestressed tightwire arch made by different schemes of cable and skewback anti thrust rigidity.In the end,some suggestions for design are presented.
