We recall from the equation for the buckling load that it is a function of I, the second moment of area of the cross-section: So for a given cross-section, a column will always buckle about the axis with the lower second moment of area, the ‘weaker’ axis. This assumes that both axes have equal restraint. stream stinger transitions
