  A concentrically braced frame (CBF) is a conventional frame to provide lateral strength and stiffness. CBFs have less ductility and energy dissipation capacity. Studies on the lateral behavior of CBF show that the ductility and seismic behavior of these frames are intensively affected by the compression element behavior; and stiffness and strength reduction after the compression element buckling decreases the CBF performance under cyclic loading considerably. In this paper, a steel yielding device constructed with waste materials is proposed to improve the hysteresis performance of the CBFs. The hysteresis performance of the proposed device is studied through experimental and numerical studies. Experimental and numerical studies show the stable hysteresis performance of the proposed device and its appropriate energy dissipation capacity. In the case of the studied device, no strength and stiffness reduction is observed up to 18 mm axial displacement. 2. On the other hand, achieving equivalent viscous damping ratio for the damper constructed with IPE80 without the use of sophisticated tools is noticeable. Manuscript profile
