［摘要］蘇遠(yuǎn)大廈中庭為一直徑達(dá)72m的多向張弦組合網(wǎng)殼結(jié)構(gòu)。詳細(xì)介紹了該工程鋼屋蓋的分析和設(shè)計(jì)，特別是下部主體結(jié)構(gòu)和支座形式對(duì)上部結(jié)構(gòu)的影響，上部組合網(wǎng)殼的靜、動(dòng)力分析及非線性屈曲分析。整體結(jié)構(gòu)的有限元分析結(jié)果表明，支座形式對(duì)空間網(wǎng)殼的穩(wěn)定性及溫度效應(yīng)的影響較大，下部主體結(jié)構(gòu)設(shè)計(jì)必須考慮上部大跨屋面結(jié)構(gòu)剛度對(duì)主體結(jié)構(gòu)自振周期的影響，張弦組合網(wǎng)殼有效改善了單層網(wǎng)殼的豎向剛度和缺陷敏感性。

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
