Theoretical effective length
Webb1 apr. 2008 · The concept of effective length is the only available common method for column design without non-linear structural analysis. Researches conducted for … 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. Theoretical analysis uses idealised end restraints, whose trans-lational and rotational stiffnesses are set to ...
