In recent years, new equipment for use in earthquake-resistant structures have been developed. Energy dissipation devices such as ADAS metallic dampers are among them which have been used in the design of the new
generation of earthquake-resisting buildings. In this study, systems with ADAS metallic dampers are evaluated in terms of behavior and performance and are compared with conventional earthquake-resistant steel systems such as the system of Chevron with steel special moment frame. Therefore, dampers needed for the design and performance of frames are evaluated by using the nonlinear dynamic analysis with Perform 3D. Also by applying the earthquake records of Bam-northridge-Elcentro-Naghan-Rudbar-Tabas-Lamaperia it is tried to obtain more comprehensive results. By installing the dampers, parameters such as relative and absolute displacement, base shear and hysteresis energy dissipation are reduced significantly by structural members and the performance of the dampers are improved with the increase in height and stories of the structure.
