A method for optimization (with some limitations) of thin-walled beams with a trapezoidal cross-section is presented in the paper. Beams are subjected to bending. They undergo local buckling in the elastic range. The dimensions of beam cross-section walls are optimized. Two cases was consider. In the first one the smallest weight of the beam (the smallest area cross-section) for given critical buckling moment was calculated. In the second case the maximum critical moment for given area of the cross-section was calculated. Next, the ultimate bending moment in the postcritical state is found for the optimized beams.
