摘　　要：考虑不同跨度、厚度、矢跨比等因素对网壳结构动力特性的影响,本文采用子空间迭代法,对板锥柱面网壳的动力特性进行了系统分析研究,在大量参数分析、计算的基础上,得出了板锥柱面网壳结构的自振规律,对板锥柱面网壳结构的抗震设计有重要的参考价值。On the basis of subspace iteration method, study on the dynamic characteristics of plate-cone cylindrical reticulated shell is systematical given in this paper. Effects of structure main parameters, such as different span, thickness, the ratio of long-span are considered in detail. Based on analysis and calculation of many parameters, rules of dynamic characteristics for plate-cone cylindrical reticulated shell are got. The results are valuable for shock-resistant design of plate-cone cylindrical reticulated shell.
