Abstract

At Kure City and Kumano-cho,Aki-gun in Hiroshima Prefecture,the seismic intensity rose to the highest level,6 or less,in the 2001 Geiyo earthquake. This research aims to investigate the relationship of wall area index of conventional wooden-framed houses for earthquake-proof and micro-tremor property to the roof-tile damage. The micro-tremor property measurements are commonly taken to survey the earthquake damage of the wooden houses and the site ground condition. However,their close relations to earthquake damage,wall area index,the micro-tremor property are not so clear. The observed results shows that as the construction year of the house is newer,the natural frequencies becomes higher and the tile-roof damage due to the Geiyo earthquake is smaller. Concerning the relatively old houses,natural frequencies decrease as wall area index decreases,especially in the short-span direction of the house.
