In this study a thin–walled bar with closed quadratic cross-section is considered. The elastic stability of axially compressed bar related to the cross–section distortion is investigated. The governing differential equation is derived with aid of the principle of stationary total potential energy. The critical load for the simply supported bar is found in analytical form and it is compared with the FEM solution. Sufficient accuracy of the results is worth of noticing.
