| This thesis presents a systematic study on the dynamic characteristics of both single-layer and double-layer cylindrical lattice shells. Based on the finite element analysis of hundreds of calculations that are selected according to various structural parameters, the characteristics of frequencies and models are induced, and the variation characteristics of the fundamental frequency of the shells with various structural parameters are obtained. Then, the practical charts of the fundamental frequency for cylindrical lattice shells are proposed by collecting and arranging the result of finite element analysis. Finally, the charts are validated by specific examples.
