Abstract:
Concentrically braced frames are commonly used as lateral resisting systems in steel structures. They provide high stiffness but have low ductility because of out-of-plane buckling [1, 2]. Energy-absorbing dampers can serve as effective damping systems [3-6]. By forming plastic hinges, these dampers prevent structural members from entering the nonlinear phase and buckling bracing members at intermediate seismic levels. This reduces the dynamic response of the structure to seismic loading
