A new yielding damper, called Bar Damper (BD), made of a number of solid bars sandwiched between two plates is introduced in this paper. Based on a simplified mechanical modeling, design parameters were formulated. The device is shown to have stable hysteretic behavior under cyclic loads. The device is capable of undergoing large displacements without significant strength and stiffness degradation. The slenderness ratio of the bars is a crucial design parameter controlling the effective stiffness and energy dissipation capacity of the dampers. Strength of the devices estimated from theoretical models developed herein is found to be consistent with experimental results.
