抄録

We studied wooden house damage during the Geiyo earthquake in 2001 based on the damage ratios around observation sites, detailed damage survey of twenty-nine houses in Saijo-cho and Kurose-cho in Hiroshima prefecture, and parametric response analyses of a wooden house model. In conclusion, the damage of roofs occurs over 5.0 of JMA seismic intensity or 200 Gal of the peak ground acceleration. As the seismic motion intensity level increases, the damage of walls begins to occur. However the correlation of the damage of walls and roofs was not high since the latter corresponds to inertia forces while the former corresponds to story deformation.
