Abstract
Considering the seismic hazard of locality and aging deterioration of a building is indispensable, to estimate the effectiveness of Earthquake countermeasures for a big earthquake assumed to occur dozens of years later, to investigate necessity of maintenance to make an building of high performance for long life. Therefore this paper suggest the idea of earthquake countermeasures for local wooden house through the case study for traditional wooden houses by using a previous seismic risk evaluation technique that can consider durability and deterioration of a building.
