Abstract : The purpose of this article is to analyze the effect of the load position (load height parameter) on the elastic lateral torsional buckling of the cantilever steel beams, under combined bending and axial forces. A nonlinear kinematic model based on higher order theory is used applicable to both short and long thin-walled box beams. In this kinematic model of higher order theory incorporates additional flexibility terms which are linked to the effects of shear, distortion and warping, it accurately predicts the lateral torsional buckling of the straight box beams. Ritz’s method is adopted in order to obtain the governing equilibrium equations, then the buckling loads are computed by solving the eigenvalue problem basing on the singularity of the tangential stiffness matrix. The proposed method is efficient and accurate in lateral torsional buckling predictions, when compared with the commercial FEM code ABAQUS results Keywords - Lateral Buckling, Thin-Walled, Height Parameter, Box Beams, Ritz’s Method
