[提要]  以一双层圆柱面网壳为研究对象，利用动力时程分析的方法，研究了此类结构的地震反应特性。讨论了地震波输入方向、水平约束刚度、不同地震波对结构地震反应的影响，并将时程分析与反应谱法的结果进行了对比，在此基础上对抗震设计工作提出了建议。

By time-history analysis,the characters of earthquake analysis of the double layer cylindrical lattice shell are studied based on one example. The earthquake wave direction, horizontal restraint rigidity, and different earthquake waves are considered, and the results by time-history analysis and response spectrum method are compared. At last, the suggestions on aseismic design are applied.
