Abstract

This paper analyzes the stability of double-T elements with complicated loading under bending moments and extra torsional moments. In the case of simple bending, long elements and elements of small cross-sections are under bending and torsion moments. Here, an extra torsional moment is also evaluated that can occur in construction 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 the energy method to calculate critical bending forces and extra torsional moment values. Obtained analytical equations are tested by experiment and present to be acceptable.
