摘　　要：为研究刚性索穹顶结构的性能,以跨度为60m的肋环型刚性索穹顶结构为例,分别对其进行在满跨和半跨均布荷载作用下的静力性能和动力性能分析,得到结构的固有频率及相应的振型,并与相应的肋环型索穹顶结构相比较,总结了杆件内力和位移的变化规律。结果显示在满跨均布向下荷载作用下,肋环型刚性索穹顶结构的性能较为优越;在半跨均布向下荷载作用下,肋环型刚性索穹顶结构的性能略有改善;在满跨及半跨均布向上荷载作用下,两者性能较为相似。肋环型刚性索穹顶并没有显著改变现有肋环型索穹顶的动力性能。In order to find out the behavior of rigid cable dome, a 60m-span Geiger rigid cable dome structure under full span uniform load and half span uniform load was studied. The natural frequency and corresponding mode of vibration, the changing patterns of member force and displacement were obtained by static and dynamic behavior analysis. Comparing with the conventional cable dome,conclusions were obtained as follows：the behavior of Geiger rigid cable dome is superior under full span uniform downward load, the behavior of Geiger rigid cable dome is slightly improved under half span uniform downward load, the behavior of Geiger rigid cable dome is similar with Geiger cable dome under full span and half span uniform upward load,the dynamic behavior of Geiger cable dome is not notable changered by Geiger rigid cable dome.
