摘　　要：考虑地震波的行波效应,采用不同的视波速,对单层柱面网壳结构在行波激励下反应分别进行了弹性和弹塑性计算分析,并与在一致激励下的地震反应进行对比,考察了两者之间的差异,深入分析了大跨度单层柱面网壳结构在行波激励下的地震反应规律,并得出了一些有益于工程实际的重要结论。In this paper, different apparent wave velocities are used in the analysis in order to consider wave-passage effect. And steel is assumed elastic and elastic-perfectly plastic material respectively. Seismic responses of long-span single layer cylindrical reticulated shell under wave-passage excitations and uniform excitations are studied, and comparison is made. The rules of seismic responses of reticulated shell under wave-passage excitations are analyzed deeply, and some important conclusions are obtained.
