| Outline of Final Research Achievements |
Japan where the percentage of the forest area accounts for 2/3 of country area is among the top countries with the most forests. The wood self-sufficiency rate of Japan is about 20 percent, because we dependent on imported wood from foreign countries. Sanin-district where about 80 percent of the total area is a forest may have potential for development by effectively utilizing local wood. So the new structural system was developed to awaken to new demand of local wood. The structural type adopted the vault structure system to which the load is mainly transmitted by compression force, it's because a wood has the high compressive strength. The cedar LVL made of local wood was employed as the structural member. We plan for structure of large space construction system with the mechanical rationality by utilizing small size timber. The performance of the constructed vault structure system was confirmed by construction test of 6 m prototype.
