摘要
本文从文献[1,2,3]中按一定的筛选原则,挑选出49组主、余震震级资料,通过回归分析,统计出了主震震级与余震震级之间的经验公式。然后,从结构在主、余震作用下的反应分析和抗震设计的需要出发,给出了确定主余震地震动时程曲线的方法,并以文献[4]为基础,确定了主震与余震的随机地震动模型及其参数。
In this paper,fouty-nine groups of magnitudes of mainshock and aftershock are chosen from Ref. [1,2,3]by some chosen principles and the relationships between magnitudes of mainshock and aftershock are obtained by statistical method. Then, in order to meet the needs of aseismic analysis and design, the method which determining the history of main-shock and aftershock ground motion is given. In the end, based on Ref. [4] the random process models of earthquake ground motion for mainshock and aftershock are established and the parameters in these models are determined.
