Abstract

In this study, the authors developed a damage evaluation method in terms of a damage spectrum that represents the relationship between the damage index DI of the entire building and the natural period of the building. The DI values obtained from the damage spectra were compared with the damage levels of RC Buildings affected by the Great East Japan Earthquake. As a result, the DI values and the damage levels showed good correspondence for the buildings in accordance with the old seismic standards. On the other hand, as for the buildings in accordance with the new seismic standards, it was found that an effect of overstrength on DI value of buildings should be considered. Furthermore, it is suggested that the present method may enable to make seismic evaluation considering the impact of aftershocks feasible.
