Experimental and numerical studies on the cyclic performance of structural frames equipped with bar dampers

This study presents the effectiveness of a new metallic damper called bar damper (BD) in improving the cyclic performance of a semi-rigid frame. The BD consists of solid bars sandwiched between a top and a bottom plate. These solid bars dissipate the applied external energy through plastic deformati...
