The load-deformation relationships including post buckling and deteriorating behaviors of wide flange section steel members are investigated in this paper. The analytical method previously proposed for box-section members are applied to wide flange section members based upon the ultimate behavior of stub-columns. The stress-strain curves of stub-columns with wide flange sections are expressed by standerdized width-to-thickness ratios of flange and web plates, which are derived by statistical treatment of previous experiments. The caluculated load-deflection curves of beams and beam-columns coincide very well with experimental results, especially in the deteriorating range.
