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。
In combination with the design of prestressed arch roof truss in a gymnasium, the optimization and finite element analysis of prestressed cable arch structure are studied. The influence of different cable schemes and arch anti-push stiffness on the internal forces and deformation of prestressed cable arch structure are compared , And put forward some specific design proposals.
