| 摘 要： | 奥运羽毛球馆弦支穹顶直径93m,为目前世界跨度最大的弦支穹顶结构。对其建立有限元模型,进行动力特性分析,提取结构前60阶自振频率和模态振型得出,结构模态频率密集,振型以中间张弦穹顶竖向振动为主等特点;合理选取地震波对结构进行水平和竖向地震时程分析,提取结构上部网壳与下部索杆在地震作用下的动内力变化数值,并与反应谱法结果进行比较,得出结构径向杆件地震动反应最大,水平向地震起控制作用等特点,可为相关结构的抗震设计提供参考。

| Abstract: | The steel roof suspend-dome structure of the badminton gymnasium is the maximal suspend-dome structure in China by now, the maximal diameter of it is 93 meter. A finite element model of the structure is set up and the analysis and research on the dynamic characteristics of the structure are done; the forward 60 natural frequency of vibration is extracted, and then it is concluded that the model has closely distributed modes, more vertical modes and many symmetrical modes. A proper seismic wave is chosen to ... |
