The goal of this paper is to propose structural joint methods for steel and wood hybrid buildings. The proposed joints are developed to allow easy and accurate construction. These consist of dowels and the non-shrink mortar or resins filled in the gap around the dowels. A series of loading tests optimized the effect of end distance and dowel pitch to the shear strength of the joints. The results are as following: (1)Wider dowel pitch results in a slight increase in the yield and maximum strengths. (2)In case of specimens with the outer layers parallel to the loading direction, the shorter end distance provoked the shear-out in the outer layers that caused the lower strengths. (3)Specimens with the outer layers perpendicular to the load showed higher strengths without any brittle failure, even with the shorter end distance.
