摘　　要：多年来,国内外地震工程界存在着一个严重缺陷,即地震学与结构抗震两者之间缺乏联系。随着基于性能的地震工程学(PBEE)的出现以及不断发展,地震学的重要性日益凸显。在结构抗震设计和分析中,强震地面运动特性的变异性对于结构地震需求的影响最大,其主要可以用幅值、频谱特性和持时3个基本要素来表示。震害经验表明,各类结构的震害表现为这3个基本要素综合影响的结果。因此,通过研究强震地面运动特性对于结构地震需求的影响,将地震工程学与结构抗震有机地结合起来是一个必然的发展趋势。The lack of a relationship between seismology and seismic resistance of structures has been a serious disadvantage in domestic and foreign earthquake engineering community over the years. Seismology is becoming more important than before with the appearance and development of performance-based earthquake engineering （PBEE）. The uncertainties of earthquake ground motions, especially amplitude,frequency content and duration, are the most important factors which can influence structural seismic demands. Previous seismic disasters have shown that the comprehensive effect of three essential characteristics dramatically effected collapse and failure of all kinds of structures. Earthquake engineering and seismic resistance of structures can be combined through the research on the influence of characteristics of earthquake ground motions on structural seismic demands.
