In this paper, a new moment resisting joint for timber houses with narrow widespan is proposed. This joint is formed by putting one beam between two columns and these members are grooved with sawtooth-shape section in their panel zone area. To grasp the structural characteristics of this system, double shear experiments and bending ones were carried out. To compare the results with the ones of non-groove joints, it was found that this system demonstrated high rotation rigidity by meshing grooves each other in early stage. Ultimately share bolts worked in cooperation with the grooves complementarily and they realized high strength.
