Calculation of Critical Lateral-Torsional Buckling Loads of Beams Subjected to Arbitrarily Transverse Loads

In this paper, the problems existing in the present theory on flexural-torsional buckling of structures are discussed, and the buckling procedure is found to be restricted to certain development order of displacements and rotations by the present theory. A fresh idea is, therefore, proposed for the mathematical description of actual flexural-torsional buckling procedure of structures. New geometric equations are formulated and a set of new potential variational equation and neutral equilibrium equations are got for the flexural-torsional buckling analysis of structures. Examples are given to detect the numerical difference between the modified theory and the present accepted theory.
