Outline of Final Research Achievements

In this report, we developed a numerical analysis method to be able to trace collapsing process of wooden houses by tsunami load. We developed the new numerical analysis program that employed distinct element method and computational fluid dynamics. The numerical simulations for two story wood houses were carried out by using our developed program. As a result, it was found that our new analysis method could carry out the collapsing process simulation include the overturning of wooden houses by post-and-beam construction wooden houses and further research was needed for precise calculations.
