[提要]  福建省体育馆屋盖为球面网壳结构，跨度达91.9m，主体结构竖向及平面布置复杂，层3环形楼层外挑7.5m，给结构设计带来较大难度。着重介绍该体育馆屋盖结构设计以及在主体结构设计中对结构布置和计算模型的考虑及处理措施，论述空间作用对这种中部空旷、柱网不规则且竖向受力复杂的框架结构的影响，可供同类结构设计时参考。

The structural design of Fujian Provincial Gymnasium is introduced, whose plan and elevation are very complicated. The roof of the stadium is a latticed grids of 91 .9m span. The structural type of the stadium, the treatment of structural model and the integrity analysis about the hollow building are discussed, which may be a reference to the similar projects.
