WebMar 5, 2024 · The lowest value of the buckling coefficient \(k_c = 3\) corresponds to two half-waves in the loading direction and one half wave in the transverse direction. It is seen that restricting the in-plane deformation does not change the buckling mode but reduces the buckling load by a factor of \(3/4\). The reaction compressive force makes the plate ... 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 factor increases to match the .92 value used for the Euler equation. CC represents co—on column length in the equations when the stress equal to K. L and r are effective length
