摘要: 彈塑性時程分析中,地震波的合理性和準(zhǔn)確性對計算結(jié)果影響較大. 為了合理地選取地震波,需要對地震波的特性有一定的了解. 對地震三要素中幅值、持時和頻譜特性的各自特點(diǎn)以及定義方法進(jìn)行了詳細(xì)闡述,并且綜合敘述對比了各國多種選波方法. 同時,簡要介紹了國內(nèi)常用的雙頻段選波法和規(guī)范 ASCE/ SEI 7?16 選波法.最后提出了一套可行選波流程,為工程師選取地震波提供參考.
關(guān)鍵詞: 彈塑性時程分析; 地震三要素; 選波方法對比; 選波流程

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
