In Japan high seismic performance is demanded to the school buildings, because they must accommodate students and regional peoples in safe during and after the severe earthquakes. However, many of these gymnasiums built before 1981 do not meet the present Japanese national seismic regulations. A seismic diagnosis and upgrading of these gymnasiums have been carried out in Japan. In this study, seismic performance of the school gymnasiums in the Cyugoku district are introduced from the database built on the basis of 323 seismic diagnosis reports. Seismic damages of these gymnasiums according to 2000 Tottoriken-Seibu earthquake and 2001 Geiyo earthquake are introduced.
