In this research, the composition types of hinge joints in wooden structures using bolts, drift pins, and lag screws as joint fasteners were investigated and the characteristics of the joint type were analyzed. The types of wooden joints using steel fasteners were classified into timber-timber, timber-steel, timber-timber-timber, timber-steel-timber, and steel-timber-steel concerning the composition. Also, it was found that the types of timber-steel-timber and steel-timber-steel were widely used by the case study on the examples of large-space buildings. Accordingly, for a comparison the shear resistances in the types of timber-steel-timber, steel-timber-steel and timber-steel were estimated in models of same member size condition. At the result, it was figured out that the type of steel-timber-steel can easily achieve shear resistance with smaller number of fasteners relatively. The type of timber-steel-timber requires the more cross-section or higher material strength at the same condition, but it seems to be widely used because it has advantages in fire resistance conditions and aesthetics. The type of timber-steel for single shear connection using lag screws presented low resistance at the same condition, but it is a useful type to create a large-space structure system as it is easy to increase resistance through increased mechanical strength of the screw.
