The paradox of torsional buckling
Within this paper, the background and the substance at a surprising fcrmation of the torsional bucking loads for thin-walled columns with variable, bisymmetric I-sections is prevented. Appropriate reference to flexural buckling and to the originally investigated neighbouring problem of free torsional vibrations is made. Author's opinion on possible existence of similar features in coupled flexural torsional eigenvalue problems is expressed.
