In this paper, the structural characteristics of beam-to-column connection under bi-axial loadings are investigated by FEM analysis. Parameters are the structure shape and the loading pattern. First, the elasto-plastic behavior of each column, beam and joint panel in structure are investigated. Next, it is clarified that the plastic deformation of joint panel gives the influence to the elasto-plastic behavior of the flange connected part and the web connected part at beam-end. The analysis results show that the plastic deformation of the joint panel is a factor that reduces the bending strength of the beam-end. Finally, the full plastic bending strength of beam-end is evaluated by taking into consideration the influence of the plastic deformation of joint panel.
