Webbis the effective length, is the radius of gyration, is the second moment of area (area moment of inertia), is the area cross section. For slender columns, the critical buckling stress is usually lower than the yield stress. In contrast, a stocky column can have a critical buckling stress higher than the yield, i.e. it yields prior to buckling.
