Novel self-resetting energy dissipation steel structure node

The invention discloses a novel self-resetting energy dissipation steel structure node. The steel structure node comprises an H-shaped steel column and an H-shaped steel beam, one end of the H-shaped steel beam is vertically connected with a flange of the H-shaped steel column through angle steel, energy dissipation dampers are symmetrically arranged between an upper flange and a lower flange of the H-shaped steel beam and the flange of the H-shaped steel column, the energy dissipation dampers are connected with the flange of the H-shaped steel column through damper upper supports, and the energy consumption dampers are connected with the flange of the H-shaped steel beam through damper lower supports; the steel structure node further comprises a plurality of prestressed cables, the prestressed cables are symmetrically arranged on the two sides of a web plate of the H-shaped steel beam and are parallel to the span direction of the H-shaped steel beam; and a plurality of prestressed cables vertically penetrate
