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