Elastic buckling mode jump (BMJ) mechanism to generate flag-shaped hysteretic damping. Eccentric capped column design to control onset of buckling and improve damping. Self-centering behavior and reusability. Analytical model of BMJ behavior for design guidance. Seismic lateral system using BMJ performs well and without residual drift.
