摘　　要：弹塑性时程分析中,地震波的合理性和准确性对计算结果影响较大。为了合理地选取地震波,需要对地震波的特性有一定的了解。对地震三要素中幅值、持时和频谱特性的各自特点以及定义方法进行了详细阐述,并且综合叙述对比了各国多种选波方法。同时,简要介绍了国内常用的双频段选波法和规范ASCE/SEI 7-16选波法。最后提出了一套可行选波流程,为工程师选取地震波提供参考。In the elastic-plastic time analysis, the reasonableness and accuracy of the selected seismic waves have a large impact on the calculation results. In order to select a reasonable seismic wave, a clear understanding of the characteristics of seismic waves was required. The characteristics and definition methods of amplitude, holding time and spectral characteristics were elaborated respectively, which are known as the three elements of earthquake. Furthermore, a comprehensive description and comparison of various wave selection methods were presented in various countries. At the same time, the commonly used dual-band seismic wave selection method and the standard ASCE/SEI 7-16 wave selection method were briefly introduced. Finally, a feasible process of selecting seismic wave was given, which provides a reference for engineers to select seismic wave.
