The ultimate strength of elasto-plastic columns under the condition of parametric resonance is presented in this paper. Special attention is paid to the influence of the initial crookedness, the magnitude of the periodic and static axial force, slenderness ratio and the Bauschinger effect on the dynamic behavior.
The dynamic characteristics are obtained by using a numerical in-plane dynamic analysis which takes both the geometrical and material nonlinearities into account.
