Beam column node structure with mutually hinged beam columns and continuous bending moment in building structure

The invention discloses a beam column node structure with mutually hinged beam columns and continuous bending moment in a building structure. The beam column node structure comprises columns and beams. The columns are concrete filled steel tubular columns and comprise circular steel tubes and concrete filled steel tubes poured into the steel tubes. A round of annular bottom sealing steel plates are arranged on the outer tube walls of the steel tubes in the radial direction, the outer tube walls of the steel tubes are further provided with a plurality of vertical shear-resisting ribs, and the shear-resisting ribs are fixed to and connected with the upper surfaces of the bottom sealing steel plates. The beams comprise floor reinforced concrete straight beam bodies and reinforced concrete ring beam bodies, the concrete filled steel tubular columns are sleeved with the reinforced concrete ring beam bodies which are borne on the bottom sealing steel plates and fixed to and connected with the shear-resisting ribs,
