Webb25 dec. 2012 · The effective length sometimes result in flawed results. For example in fixed ended column under compression, the theoretical effective length is 0.5L that is the distance between "points of contra flexure". I have done about 120 experiments on columns (fixed, simply supported) at no point of time i have seen the contra flexure shape !! WebbThe effective length of the column depends on its support reaction or end restrained. 1. If the end of the column is effectively held in a position restrained against rotation at both ends = 0.5 L. 2.

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.
