| Research Abstract |
In order to investigate recoverability of timber houses after a severe earthquake, structural performance tests of timber frames and earthquake response analyses were conducted. Several types of strengthened frames and recovered frames were loaded until they lay down on the basement to obtain their structural characteristics, and based on the data the earthquake response analysis program was fixed. On the program various types of strengthened timber house models were attacked by several famous earthquakes and their aftershocks. As a result, among 104 examined cases, there was only one case having collapsed by aftershock, without collapsing by a main shock.
