	In the paper an application of the maximum principle to designing a cross section of a still frame under several loading schemes is presented. The optimal height of the web under minimum volume of still as a cost function is determined. In particular the implicit and explicit conditions of state variables at characteristic points of axis of symmetry under different loading schemes are presented.
