[0020] In steel structure buildings, beam-column joints are the key parts connecting beams and columns. They not only bear the longitudinal load and bending moment of the beam, but also bear the axial force and bending moment of the column, and transmit the respective forces to the adjacent members. The main effects of steel structure beam-column joints include improving structural safety, construction convenience and reducing construction cost. According to the form of the joint, beam-column joints are divided into rigid joints and semi-rigid joints. Rigid joints generally use welding connection, which has large stiffness and good rigidity, but has high quality requirements for the connecting materials. Semi-rigid joints generally use high-strength bolt connection, which has large deformation capacity and can effectively alleviate the stress concentration of the joint under load.
