| Research Abstract |
At present there is no method of evaluation of wooden material and joint attacked by termite or rot fungi and so on. Therefore, we proposed acceleration method of bio-deterioration for real size members and joint of wooden house, and evaluated the survived strength them. As a result, we were able to establish how to make a real size wooden members and joint, and were able to accumulate data of bio-deterioration wooden members and joint. In addition, the results obtained from the bio-deterioration real size material tests were shown a good agreement between ultrasonic velocity or penetration depth of steel pin and the survived strength. The results obtained from the bio-deterioration real size joint tests were shown that the large decrease in survived strength when there is localized degradation of the joint part.
