挟み込みによる鋼板の摩擦接合用金物の長期構造性能

抄録

In recent years, the braces and knee braces have been used for a seismic retrofitting of the steel buildings. Also, the reinforcement of sectional area for steel members has been carried out. So far, the authors have proposed a new friction-type joint device that is required at the time of these reinforcements. The advantage of the proposed joint device is that it does not require bolt-holes and welding in the joint. In this paper, the relaxation tests were carried out in order to confirm the long-term structural performance. As a result, the same results as high-strength bolt were obtained.
