Sudden buckling of slender column structures may occur due to axial unforeseen overloads, imperfections or disturbances. Passive and active measures are presented to enhance the critical buckling load of a column to prevent buckling. Thus, uncertain buckling failure due to overloads may be controlled to reduce probability of failure. However, passive and active measures are subject to and also lead to uncertainties. Concepts of active buckling stabilisation are discussed with respect to uncertainties.
