The authors have planned to develop hybrid structure formed by reinforced concrete columns and glued laminated timber beams. To connect concrete the columns and timber beams, the shear force should be transferred at the joints directly by certain mechanism. The authors have planned to transfer the shear force using shear key formed by concrete and timber as a direct shear transfer mechanism. To verify whether the mechanism would be effective or not, the authors performed direct shear

The ratio of the length (h) to the thickness (t) of the shear key was selected as a parameter of the specimens, being varied from 3 to 7. The experimental results are reported in this paper, from those results the authors derived the following conclusions;
