A friction damper is one of useful displacement-depending energy dissipation devices; however, it necessary to obtain the mechanical characteristics each material through various experiments. Also conventional design methods obtaining optimal stiffness distribution adjust response story drift angle target values inconvenient for dampers. In this paper, dynamic loading tests dampers with different kinds materials are conducted, and compared. Further, an alternative method response-controlled structures distributions based on strength index proposed, their validity confirmed.
