| Research Abstract |
A comprehensive survey has been performed regarding the effect of strong motion duration on structural damage. In Japan, most of huge earthquakes have been occurred along the subduction zone of Japan trench. The strong motion generated by these huge earthquakes have very long duration such as 2 or 3 minutes, and the structural damage due to ground motion depend on not only the level of intensity, such as a peak acceleration, but also the ground motion duration. Since the effect of duration on structural damage differs in types of structures, the study has been focused on this point and the application to the seismic design codes for each individual civil engineering structures.
