Abstract
This work deals with the effect of shear deformation on the lateral buckling elastic of tapred thin thin-walled beams. However, a nonlinear geometric beam theory is presented according to a new kinematic model that takes into account the components of shear deformations. Ritz's method is applied to obtain equilibrium equations, then the buckling loads are evaluated by solving the eigenvalue problem by requiring the singularity of the tangential stiffness matrix. The elastic lateral buckling resistances given by the proposed method are generally in good agreement with the ï¬nite element simulation using Abaqus software and other available numerical simulations.
