| Research Abstract |
It was appeared experimentally that extractives involved in heart wood of Sugi was effective for biodegradation, and also that thick Sugi boards were usable as a good appearance plank floor or/and vertically aligned plank shear wall having high performance by inserting innovative H-shape metal fasteners in the interfaces between adjacent boards. Furthermore, it was shown that by inserting Sugi compression wedges into the parts where embedment was anticipated, the bearing property of Sugi was highly improved in comparison with no reinforcement. Consequently, some structural components utilizing material characteristics were developed and mechanism of their strength enhancement was analyzed.
