| Outline of Final Research Achievements |
In this study, the author estimated fragility curve for wooden houses built in snowy region by heavy snowfall and string ground motion. First, it was found the risk of human damage due to snow removal on roofs using statistic data for human damages in winter of Hokkaido. Next, it was found the damage risk of wooden houses affected by heavy snow load using drawings of existing wooden houses. In addition, the fragility curves of string ground motion during winter in each snow load were estimated by seismic response analysis. As the result, it was found that damage of wooden houses with roof snow was large even if seismic intensity 5 lower.
