摘　　要：瓯海奥体中心由体育场、体育馆、游泳馆及体育配套用房组成,其中体育馆主体结构采用钢筋混凝土框架结构,屋盖采用了无环索弦支网壳结构体系,为国内外首例该结构体系工程。设计中针对屋盖结构进行了屈曲分析及抗连续倒塌分析,结果表明结构的整体稳定性较好、抗连续倒塌能力强,进一步证明了结构体系选择的合理性。对拉索索力进行了专项分析,保证在各工况组合下拉索均不破断及退出受拉状态,且刚度退化后仍满足设计要求。Ouhai Olympic Center consists of stadium,gymnasium,swimming pool and sport facilities.The main structure of gymnasium adopts reinforced concrete frame structure,and the roof adopts crossover cable-supported reticulated shell structure system,which is the first project of this structural system in the world.In the design,buckling analysis and anti-progressive collapse analysis were carried out for the roof structure,the results show that the overall stability of the structure is good and the anti-progressive collapse ability is excellent,which further proves the rationality of the structural system selection.A special analysis was carried out on the cable force to ensure that the cables will not be broken or exits the tension state under each combination of working conditions,and the design requirements are still met after the stiffness deteriorates.
