摘　　要：福建省体育馆的屋盖采用双层球面网壳结构,直径112m,跨度91.9m.本文首先介绍了该网壳结构设计中的选型与结构方案优化、荷载取值、风荷载与风洞试验以及静力分布特征等方面的问题文中还进行了动力分析,给出网壳的动力特性与地震作用下杆件内力分布特征及地震作用的影响,分析了不同的支座约束情况对网壳动力特性和地震作用大小的影响.最后分析了橡胶垫支座所起的隔振作用,并介绍支座水平推力的释放及节点处理措施.Structural analysis ＆ design of the latticed shell for Fujian Gymnasium was introduced, whose roof adopts spherical double-layer latticed shell with the diameter of 112m and the span of 91.9m. The selection and optimization of structural type, the design load, the wind load and wind tunnel experiment, and statics character were first discussed. The dynamics character, the seismic action on the latticed shell＇s pole, the effects on its dynamics character and seismic action by different supports were then analyzed. The vibration isolator of rubber support, the treatment of level thrust release and joint detail were finally introduced.
