| Outline of Final Research Achievements |
We used the small size furnace in our institute. 1 hour fire-resistance test according ISO834 standard heat curve was conducted. After 1 hour fire-resistance test specimens were kept in the furnace for twenty four hours. One of test specimens was glulam using only Douglas fir. The other was the combination of load supporting part and sacrificed part. The former was Sugi glulam and the latter was Douglas fir glulam. Because the small size furnace, test specimens were heated from only two surface, one side and undersurface. We confirmed red heat stopped for two specimens.
Next we used the full size furnace and a full size test specimen whose size was 510mm high, 300mm wide and 5.5m long. In case of the full size furnace, test specimens were heated from three surface, two sides and undersurface. The same fire-resistance test as small size specimens was conducted. After 1 hour fire-resistance test specimens were kept in the furnace for twenty four hours. We also confirmed red heat stopped.
