Abstract: A self-centering cable includes a restoring and energy-dissipation unit and a cable reinforcement connected to the restoring and energy-dissipation unit by a connecting unit. The restoring and energy-dissipation unit includes an outer trough, an axial tube provided in an opening at the upper end of the outer trough, two inverted U-shaped mild steel members provided side by side and fixedly mounted in the outer trough, an axial pallet sandwiched between and fixedly connected to the two inverted U-shaped mild steel members, and a disc spring set provided in the outer trough and sleeved onto the axial tube. The cable reinforcement includes a tensile reinforcement penetrating into a reinforcement bottom connector and a reinforcement top connector. The reinforcement bottom connector is connected to the axial tube, the top end connector, connected to the reinforcement top connector, and a bottom end connector are connected to a structure to be reinforced.
