Seismic Response Analysis of Cylindrical Reticulated Shell Under Traveling Wave Excitation
摘要
Abstract
Taken a dry-coal-shed in a power plant as an example, the seismic responses of a long span cylindrical reticulated shell under horizontal uniform and traveling wave excitations are analyzed using finite element method. Based on the calculation results, the seismic responses of the structure under the two seismic inputs are compared. The numerical analysis shows that there are large differences between the peak values of the structures seismic responses under different seismic excitations and basically, the values change monotonously with the traveling velocity. Further research shows that at a specific traveling velocity, some of the structured responses are not consistent with the monotonous change tendency and the phenomenon of traveling wave resonance exists.关键词
