Webcolumns. The Euler buckling stress for a column with both ends pinned and no sidesway, F< = (/A)2 (1) can be used for all elastic column buckling problems by substituting an equivalent or effective column length Kl in place of the actual column length. The effective length factor K can be derived by performing a buckling anal WebThe effective length for each member can then be calculated from Lc = PI x SQRT( EI / Pcr ). Put simply, the effective length of a member is the length of an equivalent pin-ended strut that has an Euler buckling capacity equal to the axial force in the member at the point of frame buckling.
