抄録	Joints with axially loaded glued-in hardwood dowels were studied. A dowel whose length is ten times as long as diameter is glued into a loose-fit hole. The dowelhole clearance is filled with flexible polyuretane adhesive to relieve shear-stress concentration along a bond line. A series of pull-out tests was conducted to reveal effects of a number of parameters. Consequently, withdrawal strength of proposed joint with single dowel of 12 mm in diameter was proved to be about 18 kN. Simple theoretical expressions based on Volkersen model for a lap joint fitted well for various conditions. End joint of beams, corner joint of frames and post-sill joint were designed as applications. Moduli of rupture for the moment-resisting joints observed in experiments were approximately 30 MPa, which corresponds to the strength of Japanese-cedar timber.
