Damping steel coupling beam with high energy consumption

The utility model discloses a damping steel coupling beam with high energy consumption. The damping steel coupling beam comprises a box type section steel coupling beam, a plurality of parallel structural steels are surrounded all around the outer surface of the box type section steel coupling beam and are mutually arranged with intervals, the major axes of the sections of the structural steels are parallel to the length direction of the box type section steel coupling beam and the structural steels are arranged on a connecting plate in a the beam length direction of the box type section steel coupling beam in parallel so as to form a steel sleeve; the box type section steel coupling beam is internally provided with a plurality of precast concrete blocks. According to the damping steel coupling beam provided by the utility model, by adopting a joint function of an outer surface steel sleeve and the inner prefabricate concrete blocks, the local buckling deformation of the box type section steel coupling beam at the elastic plastic stage by a buckling restraining device, therefore an aim of improving the energy consumption capacity of the coupling beam can be improved, and the problem that the energy consumption capacity is severely degraded due to the excessive local buckling and formation of an ordinary steel coupling beam under an earthquake action can be overcome.
