Wood materials have a weak point that the material strength for fiber orthogonal direction is lower than fiber direction. The purpose of this study is development of high strength and high ductility wood structural element ability to hold the larger span. In this study, the ultraviolet-rays hardening FRP are used to improve the strength weakness of wood materials. As the result, the high ductility timber structural elements were realized that applied to the drift pined joints with insert-steel gusset plate.
