[提要]  介绍了上海世贸商城多功能厅网壳设计，工程中的单向单曲拱形网壳支承高差为14m，通过合理设置支座边界约束条件，确保了网壳结构的实际受力状况与计算模式一致。结构分析时考虑了网壳两侧有山墙的竖向平面桁架，整体分析结果比较符合实际受力情况。

It is the report on the design of the reticulated shell roof of the multifunctional hall for Shanghai World Trade City. In the project,the space reticulated shell is supported by arches with difference of elevation up t0 14 meter. It is important to select correct boundary condition to satisfy this reticulated shell roof structure. At the same time, the vertical truss must be contained in the space roof calculation.
