单双层球面网壳的行波地震响应分析
|
摘要
本文考虑了地震波的行波效应,采用不同的视波速,对单双层球面网壳结构在行波激励下的反应分别进行了计算分析,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双层球面网壳结构在行波激励下的地震反应规律,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 to analyze wave-passage effect. Seismic responses of long-span single-layer and double-layer reticulated spherical shell under wave excitations and uniform excitations are studied. Numerical comparisons are done to illustrate the wave-passage effect. Also a further study about the phenomena of seismic responses of reticulated shell under wave-passage excitations has made, and some beneficial conclusions are obtained.
