WebMay 22, 2009 · Euler Buckling Formula. Consider a column of length L, cross-sectional moment of inertia I, and Young's modulus E. Both ends are pinned so they can freely rotate and cannot resist a moment. The critical load P cr required to buckle the pinned-pinned column is the Euler Buckling Load: WebThe formula for the Euler buckling load is 10 (10.6) f c = − k π 2 E I L 2, where E is Young's modulus, I is the moment of inertia of the column cross-section, and L is column length. The value of k varies with the end conditions imposed on the column and is equal to the values given in Table 10.1.
