Outline of Final Research Achievements |
In Japan, large earthquakes are expected to hit buildings including traditional timber houses. We need to improve deformation performance of these houses for prevention of collapse during earthquakes. The purpose of this research is to suggest a method that can evaluate collapse-limited deformation of traditional timber houses. Two topics, (A) suggestion of equations to estimate collapse modes and (B) analysis on effect of horizontal planes, are shown in this research.

Academic Significance and Societal Importance of the Research Achievements |
近年、2016年熊本地震など、設計時の想定を超えた極大地震による、木造住宅の倒壊被害が多数報告されている。今後も発生が予測される極大地震に対して、木造住宅の倒壊被害を軽減するため、変形性能を向上させる耐震対策が急務となっている。本研究の成果は、伝統木造住宅の変形性能に大きく関わる崩壊形を推定するという新たな考え方を提案するものであり、変形性能を向上させる耐震対策を講じることを促進できるものである。
