| Research Abstract |
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.
