雅安天全体育馆金属屋面索穹顶设计研究
|
摘要
四川雅安天全体育馆座席数约2700座,中部直径77.3m的圆形大跨屋盖采用了金属屋面索穹顶结构.对屋面材料的选取进行了介绍,结构选型研究对比分析了肋环型索穹顶、带垂直支撑肋环型索穹顶、葵花型索穹顶和葵花+肋环型索穹顶等四种形式的索穹顶,得到了优选的葵花+肋环型索穹顶.研究了金属屋面檩条的协同工作性能,发现当檩条作为结构的一部分时,其受力状态类似于单层壳体,对结构刚度的贡献很大,承担了大部分荷载,导致檩条用钢量较大,当檩条不参与协同工作时,更加经济.对选用索穹顶的静力性能、动力性能、极限承载力、抗震性能、节点分析设计、张拉施工和健康监测等关键技术要点进行了阐述,可为同类工程提供参考.
Tianquan Gymnasium which has 2700 seats is built in Ya'an, Sichuan province. It has a circle plan with a clear span of 77.3 m and its roof employs tensegrity type cable dome with metal deck. The reason why the metal deck is chosen are discussed. In the structural selection study, several structural layouts such as Geiger dome, vertical cross-braced Geiger dome, Levy dome and the Levy-and-Geiger composite cable dome are compared and the composite cable dome is chosen as the optimal solution. Cooperating analysis of the metal roof purlins and the cable dome is studied. It is found out that the purlins work like a single-layer shell, which contribute a lot to the structural stiffness and bear most of the load. This leads to high steel consumption. In this case, it is more economical to let the purlins work independently. Technical details as static performance, dynamic performance, ultimate bearing capacity, seismic performance, joint analysis, erection and structural health monitoring are introduced,providing references for similar projects.
