In steel structures, the installation of the additive and the various material is required for the purpose of improving the usability, repair and reinforcement. In most cases, welding joints and high strength bolts connections are used for the installation of such additives. But installing a bolt is accompanied by a constant partial loss of area and welding might cause the induction of the fatigue crack. Therefore, we consider the joining method using the stud pin that does not require welding and without a partial loss of large area such as a bolting joint.
