Importance of Metallic Yield Dampers in Environmental and Seismic Effects

Abstract

One of the common and feasible ways to control structural behavior under seismic effects is to use metallic yield dampers that can be easily replaced after an earthquake. Metallic yield dampers are one of the most effective and economical mechanisms for dissipating seismic energy obtained through inelastic deformation of the material. Metallic yield dampers can be installed into the system either directly into the bracing element or by placing them between the bracing system and the beam. Studies comparing frame systems with and without metallic yield dampers show that metallic yield dampers reduce frame story drifts by up to 60%. In order to increase the use of dampers and thus improve the performance of structures, especially in underdeveloped and developing countries, it is important to consider factors such as economic production and environmental sustainability as well as strength, stiffness and energy consumption capabilities in the design of metallic yield dampers.
