Seismic resilient precast concrete frame structure and construction method therefor

A seismic resilient precast concrete frame structure, comprising a prefabricated solid column, a prefabricated superposed beam, a notched T-shaped shear connector and a buckling-restrained and energy-dissipating connecting plate;

• the prefabricated superposed beam is connected to the prefabricated solid column, and the prefabricated superposed beam comprises a prefabricated superposed intermediate beam and prefabricated superposed cantilever beams respectively disposed at both sides of the prefabricated superposed intermediate beam;
• tops of the prefabricated superposed cantilever beams and the prefabricated superposed intermediate beam are connected by the notched T-shaped shear connector;
• side faces of the prefabricated superposed cantilever beams and the prefabricated superposed intermediate beam are connected by the buckling-restrained and energy-dissipating connecting plate, wherein a length-width ratio of the notched T-shaped shear connector is less than the length-width ratio of the buckling-restrained and energy-dissipating connecting plate, and a notch in the notched T-shaped shear connector is located at a bending moment zero point under a vertical load of a frame structure.
