Introduction of Quakeproof Reinforcement Levels to Conventional Wooden Houses for Drastic Reduction of Fatalities

－Basic Expressions and Test Calculations in Aichi Prefecture－

Abstract

We have learned many problems by the 1995 Hanshin Awaji earthquake. The chief cause damage was collapsed a houses. Most of the death toll accompanied collapsed houses by earthquake. This study aims at estimation anticipating risk of collapsed house. Discussion is needed in relation with earthquake resistant diagnosis score. If lower is the necessary earthquake resistant diagnosis score then reduction in resource quantity comes. Therefore, analyze change about resource quantity. On the basis of risk estimation, a comparison between the present condition and analysis result by a study was made. And we developed feasible method for the death toll reduction.
