Proposed Modification for ADAS Damper to Eliminate Axial Force and Improve Seismic Performance

A variety of yielding dampers have been proposed with different materials and configurations and constructed for various structures to improve their seismic performance. ADAS dampers are considered as energy dissipation tools to experience uniform yielding according to their specific geometry. However, the damper cannot perform ideally in large deformations due to an unexpected tensile axial force. This axial force not only creates strain...
