ABSTRACT: The post buckling equilibrium states are determined analytically. To obtain a consisten formulation of the problem, use is made of the principle of virtual displacements and the variation calculus for variable matching points. The obtained formulations are nonlinear, but can be solved exactly. Solutions are presented for four buckled configurations. The results are presented graphically for a typical railroad track no in use on main lines. The obtained results are compared with the corresponding results of other investigations.
