Outline of Final Research Achievements

In this study, the elasto-plastic behavior of the WF beam-to-RHS column connection under the biaxial loadings was investigated by biaxial loading tests and finite element method analysis. As a result, the bending strength of beam was reduced by the plastic deformation of joint panel, the factor of decrease became clear. The declining trend could be evaluated by the panel over design factor. In addition, the early fracture of beam-end connection did not occur. And within the range of practical member combination, the whole of partial frame showed the plastic deformation capacity over the required performance by the abundant absorbed energy of the joint panel, despite that the bending strength of beam decreases.
