We suggested tangent modulus which reflected on plastic region and yield stress, then estimated plastic deformation capacity by width-thickness ratio of flange which was modified by this factor However, though we examined about members under pure bending stress, we didn't examine about members with moment gradient. Then ih this study, we examined the possibility to adapt our suggested method for members with moment gradient. And we examined that difference of moment gradient influence plastic deformation capacity of members Lastly we attempted to estimate plastic deformation capacity of members by modified width-thickness ratio besides moment gradient
