Abstract

The theory of bending of thin-walled beams of open cross-sections with the influence of shear, based on the classical Vlasov theory of thin-walled beams of open cross-sections, is developed for cross-sections with one and two axes of symmetry. It is proved that the beam is subjected to bending with the influence of shear caused by forces in the plane of symmetry and in addition to tension/compression due to shear in the case of cross-sections with one axis of symmetry, and to bending with the influence of shear caused by forces in the plane of symmetry in the case of two axes of symmetry. A new shear factor with respect to bending and tension/compression is given. The principal cross-section axes are defined in accordance with the classical theory of thin-walled beams of open sections. Illustrative examples are given, as well as comparisons with the finite element method.
