In wooden structure, it is difficult to join structural members rigidly since there is no method of unifying material like welding of steel structures. The joint with glued-in hardwood dowels is the method of inserting hardwood dowels between structural members, and hardening with glue. Moment-resisting tests about joints combined with glued-in hardwood dowels and bolts were carried out. Dowels of 12mm in diameter made of hard maple are glued into column and beam members of sugi glulam with polyurethane adhesives to make joint specimens. The diameter of a bolt is 16mm, and the section of a column and a beam is 120×360mm. As a result of the test, the maximum moments was approximately 30kN・m and rotational stiffness was approximately 5,500 kN・m/rad. Moreover, we carried out horizontal load tests of a one-story portal frame used this joint. As a result of the test, the allowable horizontal load was approximately 12kN. The rigid frame wooden house structure was designed on these experimental results. The house satisfy the required seismic performance only with five rigid frames.
