    Abstract: Supplemental damping devices have been used to decrease the dynamic response of buildings subjected to wind and earthquake inputs. These devices can be generalized into the following three major types: friction devices, viscous or viscoelastic devices, and material yield devices. Lead dampers would be included in this last case, even though its characteristics do not involve yielding. A study of one of the metallic yield devices, the steel‐plate added damping and stiffness (ADAS) device, is presented. Yield force, yield displacement, strain‐hardening ratio, ratio of the device stiffness to the bracing member stiffness, and ratio of device stiffness to structural story stiffness without the device in place have been identified as the most important parameters to characterize the performance of this device. The influence of these parameters on earthquake response of building structures is analyzed. The results show that these devices can substantially increase the energy dissipation capacity of a structure and significantly reduce the energy dissipation demand on the framing members of a structure.
