The RRD scheme is one of the innovative passive structural controller technique which increase overall lateral stiffness of structure under dynamic loads. The RRD also offer additional damping characteristic at a specified range of frame lateral displacement. The developed system is applicable for high rise structures or residential buildings in seismic prone zone. Moreover RRD element is installed in structural frames such as damper connection that is able to dissipate any type of vibration induced by dynamic load such as seismic and wind load through the shear action of embedded rubber in aforementioned system. In this study a variety of Rubber and bonding materials between steel plates are considered and evaluated in light of dynamic analysis and finite element simulation under monotonic displacement. The results observed in terms of energy dissipation value of models were compared and finally then the best material’s specifications to utilize in RRD have been introduced.
