Anti-seismic tough fabricated concrete frame structure and construction method thereof

The invention provides an anti-seismic tough fabricated concrete frame structure and a construction method thereof. The frame structure comprises prefabricated solid columns, prefabricated superposed beams, T-shaped shear connectors with notches and buckling-restrained energy consumption connecting plates. The prefabricated superposed beam is connected with the prefabricated solid column, and the prefabricated superposed beam comprises a prefabricated superposed middle beam and prefabricated superposed cantilever beams arranged on the two sides of the prefabricated superposed middle beam; the tops of the prefabricated superposed cantilever beam and the prefabricated superposed middle beam are connected through a T-shaped shear connector with a notch, and the notch in the T-shaped shear connector with the notch is located at the zero point of the bending moment of the frame structure under the action of a vertical load; the side faces of the prefabricated laminated cantilever beams and the side faces of the pr
