WebbThe comparison of Equations (6) and (1) shows that the effective length factor K is equal to 2 and therefore, that the effective length of the column is twice the actual length. In other words, the critical load for the column of length L, shown in Figure 3, is the same as the critical load of a pin-ended column of length 2L. Webbtive length, is critical in evaluating the stability of the column. Effective lengths given in the codes are generally greater than the theoretical values, as full rigidity at supports is difﬁcult, if not impossible, to achieve.

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.
