| Outline of Final Research Achievements |
To construct the maximum seismic response estimation method considering the input process of energy due to ground motions for existing reinforced concrete structures / steel reinforced concrete structures, substructure pseudo-dynamic tests and analytical studies on the estimation of the peak momentary input energy were carried out. The relationship between the momentary input energy and the maximum seismic response displacement and the influence of the hysteresis characteristics on the momentary input energy were obtained by the pseudo-dynamic tests. The relationship between the duration of the ground motion and the ratio of the peak momentary input energy to the total input energy was confirmed by the analytical studies. And the results of the analytical studies showed that the total input energy of elasto - plastic response can be estimated from the total input energy spectrum of elastic response.
