Abstract
Over the past few decades, world has experienced increased loss of human life and severe structural damages due to numerous devastating earthquakes. In order to reduce these damages, different dampers can be effectively used in building to control earthquake induced vibration as it can absorb and dissipate energy of seismic waves moving through building structure. The Steel Dual-Ring Damper (SDRDs) is a metallic damper composed of two concentric steel rings connected by a gusset plate which restrict buckling of braced frames and yield more in tension and compression due to its circular shape compared to other dampers. The work mainly focuses on determining the effect of cyclic behavior of an energy dissipation system with SDRDs in the brace to brace connection using ANSYS software. Parameters like stiffness, ductility and total dissipated energy of SDRDs were evaluated. Studies indicate that the SDRDs can be used as ductility member in concentrically braced frame systems.
