Abstract: The main parameters of flange section shape change of beam end flange enlarged airfoil joints are selected, and a series of specimens are derived with basic specimens as prototypes. The influence of the length and width parameters of the flange plate of the enlarged beam on the bearing capacity of the joint, the development law of the plastic hinge and the location of the joint, as well as the seismic performance of the joint are studied. The basic conditions for the design of the enlarged flange joint at the end of the beam are given, which is the seismic behavior of the steel structure. The revision of design specifications can provide reference.
