Friction damper is simpler and more stable in design than ordinary steel damper. It is easily used for seismic reinforcement which reduces the earthquake response of buildings by simply adjusting the tension introduced on the friction surface. However, when repeated friction occurs due to the earthquake load, the thickness of the friction material is reduced, the tension of the bolt is decreased and the damper performance is reduced. Therefore, in order to prevent this, it is necessary to check the performance of the bolt tension change periodically. In this study, the cyclic force test was carried out by classifying the friction surface into mill scale, sandpaper, and rusty condition, and the difference between the maximum frictional strength and the hysteretic behavior of the damper according to the surface condition was compared. In addition, a cylindrical load cell was fabricated to measure the tension change of the bolt during damper behavior.
