Resistant existing buildings or design of earthquake resistant buildings is one of the issues in earthquake prone countries. Using metal dampers as an energy consuming system is an acceptable way to control the failure of structures and improve their seismic performance. These energy absorbing systems deplete the earthquake input energy by deforming the metal parts used in them and as a result of their entry into the plastic area and creating many deformations, by increasing the damping of the structure. In structures where dampers are used, the presence of dampers reduces the energy received by other members of the structure and does not cause much deformation in them, that is, before the compression brace buckles, the damper surrenders and leads to increased ductility of the system. Among the types of dampers, TADAS is one of the most effective and economical tools for absorbing seismic input energy into the structure of triangular-shaped metal dampers. These dampers are mostly used in the bracing system and have the ability to absorb a lot of energy under the behavior of hysteresis. These dampers are embedded in the structure so that they are deformed due to the relative displacement due to lateral load. In this review article, we will review the studies and research done on this system in recent decades, and while evaluating the current situation, we will identify and discuss some research gaps for future studies.
