[提要] 介紹了上海世貿(mào)商城多功能廳網(wǎng)殼設(shè)計(jì)，工程中的單向單曲拱形網(wǎng)殼支承高差為14m，通過合理設(shè)置支座邊界約束條件，確保了網(wǎng)殼結(jié)構(gòu)的實(shí)際受力狀況與計(jì)算模式一致。結(jié)構(gòu)分析時(shí)考慮了網(wǎng)殼兩側(cè)有山墻的豎向平面桁架，整體分析結(jié)果比較符合實(shí)際受力情況。

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.
Keywords: curved surface reticulated shell; bolted spherical joint; lattice truss; quadrangular cone; restraint
