| 摘 要： | 选用40,50,60和80m跨度的K6型弦支穹顶结构,利用大型有限元分析软件ANSYS,对结构的受力性能及结构参数如矢跨比、撑杆高度、环索布置方式、初始预应力大小等对其的影响进行了分析。研究结果表明,在上层网壳杆件压力满足要求的前提下,矢跨比宜为1/8~1/6,撑杆高度为2.5~3.0m,采用四环索布置且索的预拉力宜在200~300MPa之间。可对弦支穹顶结构静力性能分析以及更多的工程设计实践提供参考。

| Abstract: | Suspen-dome is a reasonable and novel type of long-span hybrid spatial structures based upon the single-layer spherical lattice shell and the tensegrity system.The structural behavior of suspend-dome and structural parameters such as rise-span ratio,heights of struts,the number of cable rings and prestresses of cables have been analyzed by employing a computational model of the Kiewitt suspend-dome of 40m,50m,60m and 80m span and using the ANSYS software.Some valuable conclusions are drawn for the mechanics property analysis and practical design. |
