Recent years, rationalization of the joint structures is required from the viewpoint of reduction of the total cost of steel structures. As one of such effective solutions, adoption of super high strength bolts for friction type joints, which strength is more than 1,600MPa is considered in order to be a compact joint section with a few bolts and lines. However, the mechanical behavior of such joints, especially the behavior under compressive load, is not clear. Therefore, in this study, the mechanical behavior of the friction type joints with super/normal high strength bolts subjected to compressive load is discussed based on the FE analytical results paying attention to the maximum spacing of the bolts and contacting between joint surfaces.
