When an earthquake acts on buildings, dampers are effective to decrease the failure of buildings by absorbing the input energy. An object of this study is to develop a new type of friction damper, on whose matting surface aluminium is sprayed, and the double friction joint is tightened with a high-strength bolt. When the slip occurs on this friction damper, the slip coefficient is high and comparatively stable. Specimens of the friction damper are tested under single shot and continuous cyclic loading condition to investigate the effect of the condition of the sprayed surface on the hysteresis characteristics. The parameters of the test are thickness of sprayed aluminium, initial clamping force (contact pressure), loading program, kind of sprayed metal and the sprayed surface of the plate. Results indicate that there exists relationships between the thickness of sprayed aluminium and the tightened clamping force to obtain stable slip load.
