This paper reports the development of dowel laminated timber made of Japanese cedar. Single-plane shear test of wooden dowels and lateral loading test of three types of dowel laminated timber were performed. The result of tests shows that dowel laminated timber has high-ductility and enough seismic performance. In addition, the mechanical model of dowel laminated timber and method of calculating the stiffness are shown. The stiffness calculation results are in good agreement with the experimental results.
