SEISMIC PERFORMANCE AND STRUCTURAL REGIONALITY OF DAMAGED WOODEN HOUSES IN THE 2007 NOTO HANTO EARTHQUAKE

Abstract

This study performed a damage survey and seismic performance evaluation in the Kuroshima district, which was subjected to strong shaking during the 2007 Noto Hanto earthquake. From the results, the base shear coefficient for wooden structures is relatively high; 0.51 for wooden houses and 0.78 for mud-walled storehouses. The mud plaster wall, hanging walls, and spandrel walls are also an important seismic resistant element. Structural regionality of the wooden house is found in equivalent height, peculiar mode, and base share coefficient. As a conclusion, high strength of wooden structures cannot always reduce the maximum response deformation angle.
