[提要] 福建省體育館屋蓋為球面網(wǎng)殼結(jié)構(gòu)，跨度達91.9m，主體結(jié)構(gòu)豎向及平面布置復(fù)雜，層3環(huán)形樓層外挑7.5m，給結(jié)構(gòu)設(shè)計帶來較大難度。著重介紹該體育館屋蓋結(jié)構(gòu)設(shè)計以及在主體結(jié)構(gòu)設(shè)計中對結(jié)構(gòu)布置和計算模型的考慮及處理措施，論述空間作用對這種中部空曠、柱網(wǎng)不規(guī)則且豎向受力復(fù)雜的框架結(jié)構(gòu)的影響，可供同類結(jié)構(gòu)設(shè)計時參考。
[關(guān)鍵詞] 體育館 空曠建筑 整體分析 環(huán)梁剛度 預(yù)應(yīng)力The structural design of Fujian Provincial Gymnasium is introduced, whose plan and elevation are very complicated. The roof of the stadium is a latticed grids of 91 .9m span. The structural type of the stadium, the treatment of structural model and the integrity analysis about the hollow building are discussed, which may be a reference to the similar projects.
