Research Abstract	In this report, we developed a numerical analysis method to be able to trace collapsing process of wooden houses made by Japanese traditional construction method during earthquake. We used numerical analysis program developed by ourselves. As a result, it was found that our new analysis method can carry out the collapsing process simulation include the sliding behavior of columns bottom ends and the large deformation of floor diaphragms of Japanese traditional wooden houses by using the element test results of the walls and the joints.
