摘要：

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. Afresh 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 rariational equation and neutral equilibrium equations are got for the flexural-lorsional buckling analysis of structures. Examples are given to detect the numerical difference between the modified theory and the present accepted theory.
