This paper analyzes the stability of double-T elements with complicated loading under bending moment and extra torsional moment. In case of simple bending, long elements and elements of small cross-section are under bending and torsion moments. Here, an extra torsional moment is also evaluated that can occur in constructions under external effects: unsymmetrical loads, wind and temperature. Classical solutions are analyzed in various papers and studies, and engineering solutions given in standards present no examples of such a complicated loading. Therefore, this paper suggests energy method to calculate critical bending forces and extra torsional moment values. Obtained analytical equations are tested by experiment and present to be acceptable.
