Structural　control　systems　have　gained　popularity　for　the　ability　to　reduce　the　structural　vibration　response　of　civil　structures　subjected　to　different　types　of　dynamic　loads.　Passive,　semi-active,　active　and　hybrid　control　systems　have　been　widely　utilized　in　various　types　of　structures.　This　article　presents　one　of　the　most　economical　and　yet　the　most　effective　approaches　used　in　structural　vibration　control.　Herein,　a　comprehensive　state-of-the-art　review　of　the　development　and　application　of　metallic　dampers　is　discussed.　The　dampers　are　classified　into　five　categories:　steel,　aluminum,　lead,　copper　and　shaped-memory　alloy　dampers.　In　addition,　the　details　of　various　computational　methods　used　in　the　analysis　of　metallic　dampers　are　briefly　explained.　This　article　reveals　that　the　use　of　metallic　dampers　is　being　advanced　broadly　owing　to　their　low　manufacturing　costs,　stable　hysteresis　behavior,　resistance　to　ambient　temperature,　reliability　and　high　energy　dissipation　capability.　It　is　also　concluded　that　mild　steel　is　the　most　popular　material　among　metallic　dampers.　©　2019,　CIMNE,　Barcelona,　Spain.
