The aim of this research is to establish a design method for the proposed semi-rigid timber structure, which are constructed with coupled beams and columns assembled using screwed joints and high-tensile bolted joints with steel side plate. This paper is mainly focused on the verification for modeling of moment resisting mechanism of screwed joint between glulam-steel in beam-to-column joint. The proposed mechanical model takes into account shear deformation of glulam. According to the result of the conducted bending tests for beam-tocolumn joint, it can be concluded that the mechanical model estimated the initial stiffness and yeild moment of screwed joint or panel shear strength precisely. In addition, experimental slip moment of high-tensile bolted joints corresponded to the caluculation values from the existing design method. On the other hand, the experimental yield moment of steel side plates was two times higher than caluculated values from the method. The experimental rotational stiffness of steel plates bending deformation was in the same range of that of screwed joint.
