| Research Abstract |
This study developed an evaluation method of strong-motion distribution for rapid and precise building damage estimation when an earthquake occurs. The applicability of the method is checked by comparing estimated and real damage distribution in Sendai city during the 2011 Tohoku earthquake. It is confirmed that the strong-motion distribution estimated by the developed method can explain the real damage distribution relatively well, with appropriate use of nonlinear response characteristics of buildings and soil-structure interaction effects.
