The invention relates to a super-elastic self-resetting energy consumption device, and belongs to the field of energy dissipation and damping of engineering structures. The super-elastic self-resetting energy consumption device mainly consists of an U-shaped groove, an inner extending steel plate, a mild steel energy consumption plate and a shape memory alloy pull cable, wherein the U-shaped groove consists of two parallel steel plates and a vertical steel plate, the inner extending steel plate extends into the middle part of the U-shaped groove and is parallel with the two parallel steel plates of the U-shaped groove, the clear clearance between the end part of the inner extending steel plate and the vertical steel plate of the U-shaped groove is not smaller than 5cm, the mild steel energy consumption plate is arranged between the parallel steel plates of the U-shaped groove and the inner extending steel plate, and the shape memory alloy pull cable is symmetrically anchored at the two sides of the U-shaped groove and the inner extending steel plate in a crossing manner. The super-elastic self-resetting energy consumption device has the advantages that the concept is clear, the processing is convenient, the energy of an earthquake input structure can be effectively dissipated under the condition of strong earthquake, and the super-elastic self-resetting energy consumption device can be widely applied to the engineering structure needing key earthquake fortification.
