A monotone dependence of the critical buckling load of a simply supported TimoshenkoMindlin beam both on the shear correction factor and on the stiffness of foundation is proved. Then the worst-scenario method is employed to find the most dangerous input data.
Keywords: beam buckling; elastic foundation; Timoshenko model; uncertain data; worst scenario.
