The present paper deals with the buckling of thin-walled square tubes with intermediate stiffeners under torsion when the shear lag phenomenon and distortional deformations are taken into account. A plate model (2D) was adopted for the tube. The tubes were assumed to be simply supported at their ends. The values of critical loads of the tubes were determined with three methods, namely: analytical-numerical method (ANM), finite difference method (FDM) and finite element method (FEM).
