摘要
提出了弦支穹顶结构滑动环索节点的连接方式 ,应用冷冻升温结构分析方法研究其受力性能 ,并与非滑动环索连接节点的计算结果进行对比 .计算结果表明 ,当结构承受半 (偏 )跨荷载时 ,滑动环索的连接方式对上部网壳结构的受力性能几乎没有影响 ,但却可以大大降低环索、斜索和撑杆的内力幅值 ,使其均衡 。
Gliding hoop cable connection of suspen-dome structure is brought out in this paper.And frozen-heated method is employed to analyze its mechanical behavior when the structure is applied with half-span loads.Compared to the non-gliding hoop cable connection,the gliding hoop cable connection can adjust internal forces and decrease a peak value of internal forces of hoop cables and radial cables,while it has little influence on the mechanical behavior of the top lattice shell of the structure.
