Popis: Finite element analysis methods were conducted to investigate the seismic performance of panel zone at the connection of square steel column and two H-shaped beams with different heigth level by using ABAQUS. Compared with the previous test ,which verifies the correctness of finite element model. The paper sets up a total of 11 finite element analysis models, The changes of the web thickness, thickness of beam flange, diameter-thickness ratio in the finite element analysis models are studied, Which affect the beam end joint load - displacement curves and stress distribution.Studies have showed that: the beam flange thickness ratio and the beam offset ratio has insignificant influence on the load-displacement curves. The diameter to thickness ratio have sharp influence on the load-displacement curves.
