| Abstract: | With the rapid development of electric power facilities,seismic design research of high voltage electrical equipment has become one of the important topics in seismic research at home and abroad.Taking the time history analysis of large-scale DC voltage generator tower structure,which is located on indoor ground,as an example,the separate incentive responses under five amplitude modulation sine waves,three sine waves,EI Centro seismic ground motion,Taft seismic ground motion and Yunan Lancang seismic ground motion are calculated in this paper.The influence of different input ground motion on seismic response of the structure and dynamic performance under different Rayleigh damping models are discussed.Some suggestions on seismic input and choice of Rayleigh damping models for this type of structure are proposed at the end of this paper. |
