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
