［摘要］2006年建成并運(yùn)營(yíng)的江蘇省南通市體育會(huì)展中心主體育場(chǎng)是我國(guó)第一個(gè)應(yīng)用于大跨公共建筑的開(kāi)合式結(jié)構(gòu)。對(duì)該結(jié)構(gòu)的設(shè)計(jì)研究表明，開(kāi)合式結(jié)構(gòu)穩(wěn)定性分析應(yīng)考慮活動(dòng)屋蓋處于不同位置時(shí)幾何狀態(tài)與荷載分布的變化，且應(yīng)準(zhǔn)確模擬活動(dòng)部分和固定部分之間的約束條件。數(shù)值分析表明，在設(shè)計(jì)荷載作用下，南通體育場(chǎng)開(kāi)合式結(jié)構(gòu)具有足夠的整體穩(wěn)定性。

Abstract:Founded in 2006,Nantong Stadium of Sport Exhibition Center in Jiangsu Province is the first retractable structure as a large-span public building in China. In the design process, the global stability was studied. The research indicates the necessity to consider the different geometrical status and loading distribution with the movement of retractable roof in stability analysis. It is important to simulate the restraint condition of devices and linkages between retractable roof and its fixed supporting structures. The numerical analysis shows that the retractable steel roof and its supporting structures in Nantong Stadium possess full resistance against the instability risk.

Keywords:retractable structure; stability analysis; single-layer; arch-supported reticulated shell; Nantong Stadium
