Abstract
In the flexural-torsional buckling of beams, it is common practice to assume that the major axis flexural rigidity, EIx, is very large compared with the minor axis rigidity, EIy, and the torsional rigidity, GJ. That is, the in-plane deflections prior to buckling are assumed small enough to be ignored in the derivation of a method is presented for accounting for major axis curvature in the calculation of the buckling loads of doubly-symmetric I-section cantilevers and simple beams. This method involves little more effort than the conventional treatment. Beams of two different steel sections are investigated, one a column section and the other a beam section, and the results are presented in graphical form.
