摘要
考虑不同矢跨比、荷载、支座刚度和跨度等多种因素对网壳结构的动力特性的影响，本文采用子空间迭代法系统研究了Ｋ８ 型单层球面网壳结构的自振特性，得出了Ｋ８型单层球面网壳结构的自振规律；
Based on ratio of the rise span、load、rigidity of supports and span, dynamical characteristics of K8 single layer reticulated spherical shell are studied with the method of sub space iteration. The results are valuable in view of the dynamic performance research and the engineering design of reticulated shell structure.
