摘要
索穹顶结构是由索、杆及膜组成的新型预应力结构,应用在大跨度空间结构领域。利用大型有限元分析软件(Ansys),分析了结构参数(如环数、每环节点数、矢跨比等)的影响,对60m跨度Levy体系索穹顶结构的静力性能进行了研究。给出了一些合理的结构设计参数取值建议,为Levy体系索穹顶结构的设计以及工程实践提供参考。
Cable dome is a new prestressed structural form comprised of cables,struts and membranes.It has been used in long-span space structures.The structural static performance of Levy system cable dome whose span is 60m has been studied by changing structural parameters such as number of rings,number of nodes at each ring and the number of cable rings and so on and using the large finite element software(ansys).Proper scales about structural parameters have been given.They will provide some reference for the design of Levy system cable dome and project practice.
