A ductile Vierendeel frame can be constructed by incorporating steel panel dampers (SPDs) into a moment-resisting frame. The stiffness, strength, and ductility of the lateral force-resisting system can thereby be enhanced. The three-segment SPD proposed in this study possesses a central inelastic core (IC) and top and bottom elastic joints. This study discusses the mechanical properties, capacity design method, and buckling-delaying stiffeners of SPDs using cyclic loading tests for two specimens. Tests confirm that SPDs’ cyclic force versus deformation relationships can be accurately predicted using either the Abaqus or PISA3D model analyses. The peak shear deformation of the ICs in the SPDs reached 0.11 rad. The experimental cumulative plastic deformation of the proposed SPD was 242 times its yield deformation, and was capable of sustaining the maximum considered earthquake at least eight times before failure. |
