[摘要]蘇州中心“未來之翼”屋面鋼結(jié)構(gòu)南北向展開長度約630m,整個屋面呈異形曲面,且不設(shè)置伸縮縫。屋面采用并不自然共面的四邊形鋼網(wǎng)格,外覆玻璃幕墻。結(jié)構(gòu)存在超長并跨越多個支撐單體、異形曲面精度要求高等設(shè)計難點。介紹了“未來之翼”屋面鋼結(jié)構(gòu)設(shè)計中的多工況作用分析、抗放結(jié)合的支座與節(jié)點設(shè)計、穩(wěn)態(tài)分析、抗連續(xù)倒塌分析、特殊的涂裝與排水方案等。最后,介紹了施工方案的實施要點。[關(guān)鍵詞]蘇州中心; 異形曲面; 抗放結(jié)合; 抗連續(xù)倒塌分析; 施工方案中圖分類號:TU391,TU318.2 文獻標(biāo)識碼:A 文章編號:1002-848X(2015)14-0056-09
Structural design for Wing of Future steel roof of Suzhou CenterLu Jianglong1, Chen Wei2, Shen Xiaoming1, Zhu Xunyan1, Tan Lihua1(1 Suzhou Industrial Park Design & Research Institute Co., Ltd., Suzhou 215021, China; 2 Schlaich Bergermann und Partner, Shanghai 200031, China)Abstract: The Wing of Future steel roof structure of Suzhou Center has the length of approximately 630m from north to south. The entire roof features special-shaped curved surface without expansion joints. The roof adopts not naturally coplanar quadrilateral steel mesh with the outer covered glass curtain wall. There are some difficulties to design including super-long structural form with spanning multiple supporting buildings and the high accuracy requirement of special-shaped curved surface. The multiple loading case analyses, supporting and joint design considering resistance combined with release, steady state analysis, progressive collapse analysis, special coating and drainage schemes for Wing of Future steel roof were introduced. Finally, the implementation of the construction scheme was introduced.Keywords: Suzhou Center; special-shaped curved surface; resistance combined with release; progressive collapse analysis; construction scheme
