WebMar 22, 2024 · 4.0 Axis of Buckling. 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. WebFor flexural, or strut buckling, N cr, the elastic critical force, is equal to and the non-dimensional slenderness is given by: for Class 1, 2 and 3 cross-sections, where: . L cr is the buckling length in the axis considered; i is the radius of gyration about the relevant axis, determined using the properties of the gross cross-section; λ 1 = 86 for grade S275 steel
