Sažetak
The theory of torsion of thin walled beams of open cross-sections with influence of shear on the basis of the classical Vlasov´s theory of thin-walled beams of open cross-sections for beams with single and double symmetrical cross-sections is developed. It is proved that the beam subjected to torsion with influence of shear exerted by couples in the beam cross-sections is also subjected to bending due to shear in the plane orthogonal to the plane of symmetry. The beam is subjected to torsion with influence of shear only in the case of double symmetrical cross-sections. The principal cross-section axes as well as the pricipale pole are defined according to the classical theory of thin-walled beams of open sections. Illustrative examples are given, as well as a comparison with the finite element method.
