The coupled buckling behaviors of steel H-section columns are investigated by the FEM analysis including both geometrical and material nonlinearities. The FEM model is consisted of two regions, one is plated assembly to evaluate the local plate deformation and another is the beam element substructure. It is made clear that the reduction from the column strength or the local buckling strength caused by the coupling effect is affected by the cross-sectional profile. And a design formula for the coupled buckling strength that contains the cross-sectional parameter is presented. The accuracy of the formula is examined by the comparison with the experimental data and the theoretical results.
