Abstract The purpose of this study is to develop a moment frame system of a mixed structure consisting of a beam-column connection made of timber and a filling wall while verifying the structural performance of the beam-column connection using steel. The reinforcing rebar embedded on the inside of the timber beam consisted of an internal and external connection. Two connections were fabricated for each shape, and a lateral loading test was performed. The results of this experiment indicated that as the deformation of the inner and outer connections increased, repeated attachment and bearing failure occurred on the part embedded at the end of the timber beam. In addition, the fracture phenomenon of slipping was observed on the contact surface between the upper and lower flange plates of joined steel and the timber beam. While comparing the experimental behavior and the allowable bending moment of the timber beam, it was revealed that the intermediate moment frame (0.02 rad) performance of the internal connection was sufficiently secured. However, the external connection was found to be inadequate to secure the performance of the intermediate moment frame. For the beam-column connection using steel to exhibit special moment framing performance, the embedded length of the reinforcing bar embedded in the cross section of the timber beam needs to be sufficient.
