In this paper, using principal component method 115 strong-motionearthquake records are analysed.
本文运用主成份法对115个强地震运动资料进行了分析。

This modification incorporates explicitly the duration of strongearthquake ground motion into the time dependent variation of the root-mean-square peak amplitude.
这个修正明显地将强震运动的持续时间包含在均方根振幅依赖于时间的变异中。

Based on the characteristics of earthquake simulation test, a concept of fluid dispensation coefficient is developed through the analysis of typical strongmotion velocity records.
