Double lateral force resisting structure of fabricated buckling-restrained brace steel frame

The utility model discloses a double lateral force resisting structure of a fabricated buckling-restrained brace steel frame, which comprises at least one frame unit and at least one buckling-restrained brace. Each frame unit is defined by two frame columns and one frame beam to form an open rectangular frame, and two ends of the frame beam are respectively in semi-rigid connection with the upper ends of the two frame columns. The buckling-restrained brace is arranged in inclined mode, and two ends of the buckling-restrained brace are fixedly connected to the inside of the frame unit. The buckling-restrained brace is capable of being subject to pull and stress so that energy dissipation performance is good. The frame beam and the frame columns are in semi-rigid connection, only bolted connection is required at the construction site, and the brace and the structure are in bolted connection, thereby being convenient in construction and improving construction speed.
