摘要: The nonlinear lateral buckling response of perfect stocky beams in the vicinity critical bifurcational state is discussed. Attention focused on initial post-buckling response. This depends nature branching point which explored by using a (lateral) bending-curvature relationship. It found that plane loading (associated with major moment inertia) looses its stability through stable symmetric bifurcation point. Hence, above are not sensitive to imperfections, exhibiting strength. However, equilibrium path quite shallow, so load-carrying capacity such rather limited. analysis supplemented illustrative examples forI-beams for effect various parameters postbuckling also
