Abstract:In the elastic⁃plastic time analysis, the reasonableness and accuracy of the selected seismic waves have a largeimpact on the calculation results. In order to select a reasonable seismic wave, a clear understanding of the characteristicsof seismic waves was required. The characteristics and definition methods of amplitude, holding time and spectralcharacteristics were elaborated respectively, which are known as the three elements of earthquake. Furthermore, acomprehensive description and comparison of various wave selection methods were presented in various countries. At thesame time, the commonly used dual⁃band seismic wave selection method and the standard ASCE/ SEI 7⁃16 wave selectionmethod were briefly introduced. Finally, a feasible process of selecting seismic wave was given, which provides a referencefor engineers to select seismic wave.

Keywords:elasto⁃plastic time analysis; three elements of earthquake; wave selection methods comparison; selectingseismic wave process
