In a general structure, damage to the structure under an earthquake occurs mostly at beam ends due to large bending moments at the structure nodes. In the utility model, the damper 4 is arranged at the end part of the frame beam 2, so that the damage of the frame beam 2 and the frame column 1 during an earthquake is concentrated at the damper 4, and the damage of the structural beam is reduced; when an earthquake occurs, the buckling restrained brace 3 and the damper 4 work cooperatively, so that energy consumption is jointly consumed, and the overall earthquake resistance of the structure is improved.
Specifically, the buckling restrained brace 3 is arranged in an eight-shaped mode, and the buckling restrained brace 3 is symmetrically arranged.
