An kinds of researchs about buckling of web and flange afe performed as a single plate under the assumption of the boundary condition. But few researches on the coupled instability of web and flange had been performed so far. As elements of H shaped steel menbers, the behavior of web and flange is effected by earch other. Therefore, the purpose of this study is to understand the interaction between the elements of web and flange plates when coupled buckling happens. In this paper, the analysis is done with energy method. Buckling interrelation between web and flange is clarified. And a new method of evaluation of coupled buckling strength under bending-shear and axial force is proposed by using parameter of geometrical shape about web and flange of H Shaped member.
