Four buildings at the Kushiro Technical High School, damaged in the 1993 Kushiro-Oki and the 1994 Hokkaido-Toho-Oki earthquakes, were modeled as an assembly of nonlinear elements to verify our present techniques for earthquake-resistant design of structures. The input motions were independently evaluated based on the strong motions recorded on the ground at the Kushiro District Meteorological Observatory, 2km west of the school, and the soil-structure interaction was taken into account. The results of the dynamic response analysis showed a good agreement with the detail of different degree of the damage to the four buildings.
