Abstract

Abstract

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 doplacements and rotations by the present theory.A fresh idea is.therefore,proposedfor 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 diffrence between the modified theory and the present accepted theory.
- flexural-torsional buckling,
- geometric equation,
- rotations,
- order
