Abstract: The application of glued-in hardwood dowels to end-jointing of large section column timbers was considered. Test column timbers were glued laminated timber (GLT) and solid wood. Test column timbers were made of sugi (Cryptomeria japonica) and were end-jointed with hard wood dowels (Acer saccharum). In this study, we maed a series of four points bending tests to evaluated bending strength and stiffness for jointed column timbers. For GLT colums, the ratio between the experimental MOR and the calculated MOR in Type I and II were 0.809 and 0.995. For solid colums, the experimental MOR were lower than the calculated values, but variations of the experimental MOR were small. The ratio between the experimental MOR and the calculated MOR in Type III was 0.854 on average. For solid and GLT colums. the calculated deflection considering additional deflection caused by the pull-out displacement of dowels did not agree with the experimental values. This is because the end-joint cross section was glued together.
