摘要：

The paper is aimed at searching for the optimum shape of an open cross-section of a thin-walled beam under strength and stability constraints. Variational and parametrical shaping of the cross-section of the beam is employed. The stability constraints include lateral buckling of the beam and local buckling of the walls. The problem is purely mechanical one, and manufacturing constraints are not considered. The objective function is the minimal value of the cross-section area of the beam. Optimal shapes of the beam profiles are shown graphically.
