WebColumns have a safety factor Of about I .67 since the residual stresses have maximum effect but Sudden buckling is less 1 Co A. slenderness increases to Cc variable safety … Webcolumn buckling characteristic equation: ( − )( − )( − ) − ( − ) − ( − ) + 2 − − = 0 (12) As a cubic equation, there are three possible root values for P. Inserting the lowest positive root in Eq. 11 establishes the relative magnitudes of the displacement functions u, v, and φ for the controlling mode.
