| Abstract |
Friction damper is a kind of passive energy absorbing device that controls displacement and vibration in order to improve the performance of building structures and numerous studies are under way about it. Now it is developed slightly different details of shear type friction dampers, but with the surface of friction materials and friction behavior of sliding friction surface to use the same concept in the history of the pressure exerted by the frictional resistance is determined. Thus, the size of pre-tensioned bolt that is introduced is a very important factor in determining the performance friction damper. Also, the time duration for the loosening of slip-proof bolts without sliding friction is also important and the plan prepared guarantees to determine the reliability of friction damper. In this paper, the flat washer that increase the friction force and the plate type spring washer which is special heat treatment that produced by friction used and a repeated static loading is test, and the coefficient of friction of friction damper, sliding strength, bolt tension maintenance ratio and energy absorption capacity of shear type friction damper was executed. |
