Interactive buckling of thin-walled beam-columns with open and closed cross-sections
AbstractThe influence of interactive buckling on the postbuckling behaviour of thin-walled elastic beams with imperfections is studied. The investigation is concerned with thin-walled closed and open cross-section beam-columns under axial compression and a constant bending moment. The beams are assumed to be simply supported at the ends. The asymptotic expansion established by Byskov and Hutchinson is employed in the numerical calculations in the form of the transition matrix method. The paper's aim is to achieve the improved study of the equilibrium path in the postbuckling behaviour of imperfect structures with regard to the second-order approximation. The calculations are carried out for several types of beams.
