Abstract

The damage ratios of wood house in the 2000 Western Tottori Prefecture earthquake are remarkably small and are not affected by construction years compared with those in the 1995 Hyogo-ken Nanbu, Kobe, earthquake. This paper clarifies the cause of the difference in damage ratios produced by two earthquakes by demonstrating quantitative data suggesting that if houses were not influenced by decay or termite attack, damage ratios would not have varied with construction years also in the Kobe earthquake. In conclusion, we have pointed out that to reduce the damage of wood houses in big earthquakes with large return period, maintenance by owners and local carpenters is very important as well as retrofit of houses with poor seismic performance.
