摘要

地震动加速度作为计算仪器烈度的地震动参数是大家所公认的。美国Shake Map系统仪器烈度的计算利用水平向加速度峰值,日本气象厅则利用持时大于等于0.3 s的等效加速度峰值,选择何种加速度,是个值得探讨的问题,本文通过对大量强震记录的统计分析,讨论了不同持时下的有效峰值加速度和三分向合成加速度的关系。
It well be known thatthe acceleration astheimportant ground motion parameter for calculating the instrumental intensity. The horizontal peak acceleration and the effective peak acceleration has been adopted forthe rapid instrumental intensity maps for Shake Map and JMA. However,which of the acceleration will be adopted was a valuable discussing problem. The effect of filtering frequency on the peak acceleration was discussed by the statistic analysis of a large number of strong motion records,how to select the peak acceleration was discussed,the Aof which satisfies the different duration or the Aallwhich is synthesized by three components.
