［摘要］苏远大厦中庭为一直径达72m的多向张弦组合网壳结构。详细介绍了该工程钢屋盖的分析和设计，特别是下部主体结构和支座形式对上部结构的影响，上部组合网壳的静、动力分析及非线性屈曲分析。整体结构的有限元分析结果表明，支座形式对空间网壳的稳定性及温度效应的影响较大，下部主体结构设计必须考虑上部大跨屋面结构刚度对主体结构自振周期的影响，张弦组合网壳有效改善了单层网壳的竖向刚度和缺陷敏感性。

Abstract:A cable-stayed shell was adopted for the atrium of Suyuan Building, and the new structure was composed of twelve planar shells while supported by multidirection stringed beams. The analysis and design were introduced，and the effect of the boundary condition and supporting rigidity on the main building and the roof was studied. The vibration characteristic, seismic performance and integer stability of the shell were analyzed. The results show that the supporting rigidity plays an important role in the stability and the temperature effect of the shell, the multi-direction stringed beams improve the shell stability efficiently.
Keywords:cable-stayed shell；stringed beam；nonlinear buckling
