［摘要］   常州體育會(huì)展中心由體育館會(huì)展中心、體育場(chǎng)、游泳館等組成。其中體育館屋蓋采用了索承單層網(wǎng)殼結(jié)構(gòu)，該網(wǎng)殼不但跨度較大，而且是國內(nèi)外同類結(jié)構(gòu)中唯一的橢圓形穹頂，相比正圓形索承單層網(wǎng)殼，橢圓形具有各向受力不對(duì)稱，設(shè)計(jì)、施工難度更大等特點(diǎn)。介紹了該屋蓋的結(jié)構(gòu)選型，橢圓形索承單層網(wǎng)殼結(jié)構(gòu)布置、構(gòu)件截面等結(jié)構(gòu)設(shè)計(jì)基本情況，靜力、動(dòng)力和穩(wěn)定性分析內(nèi)容，以及屋蓋整體縮尺模型和節(jié)點(diǎn)試驗(yàn)及施工模擬分析情況，最后簡(jiǎn)單介紹了會(huì)展中心及體育用品商店入口單層網(wǎng)殼結(jié)構(gòu)的設(shè)計(jì)情況。

Abstract:Changzhou Sports and Exhibition Center is composed of a gymnasium and exhibition center, a stadium and a swimming gym. A cable-supported dome is employed as the roof structure of the gym. This cable-supported dome is not only a large span structure, but also the only elliptical cable-supported dome constructed in domestic and overseas. Compared with round domes, elliptical domes have asymmetry force and bear more difficulties in design and construction. The structure comparison, geometric layout, member arrangement and section selection were described. It also introduced contents of static and dynamic analysis, buckling and nonlinear static analysis, tests of an integral model and connections, and simulation of its construction procedure. Finally, the structural design of the exhibition center and a sports shops single layer shell were introduced briefly.
Keywords:Changzhou Gymnasium; cable supported dome; ellipse; static and dynamic analysis; model test; construction simulation
