| Outline of Final Research Achievements |
It was found that to locate some fasteners of timber joints with steel-plate in zig-zag line increased the ductility and the ultimate strength loaded parallel to grain, but the yield strength and the initial stiffness were not affected.
In moment-resisting joints, the yield strength and the initial stiffness were increased with consideration of the anisotropy of wood.

| Academic Significance and Societal Importance of the Research Achievements |
本研究によって、木質構造物の接合部を合理的に設計する手法を示し、実験によって検証した。これにより接合部の低コスト化や部材断面のコンパクト化が可能となり、建築物の低コスト化に繋がり、ひいては建築物の木造化の推進に寄与できるものと考える。
