Development on seismic evaluation technique for nuclear equipment and pipes based on seismic energy input

通常，抗震评估是基于荷载。荷载是一个瞬时参数，因此它不能评估地震的持续时间和余震的数量。因此，本研究采用了地震能量输入。地震能量输入可以估计地震的持续时间和余震的数量。作为使用各种试件的实验的结果，地震能量输入和破坏之间的关系被确认。因此，地震能量输入适用于抗震评价。

In general, seismic evaluation is based on a load. A load is a momentary parameter, so it cannot evaluate duration time of an earthquake and the number of aftershocks. Therefore a seismic energy input was applied in this study. The seismic energy input can evaluate duration time of an earthquake and the number of aftershocks. As a result of experiments using various specimens, relationships between the seismic energy input and failure were confirmed. Therefore seismic energy input is applicable to seismic evaluation.
