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. Table 10.1. The following model applies to columns simply supported at each end (). Firstly, we will put attention to the fact there are no reactions in the hinged ends, so we also have no shear force in any cross-section of the column. The reason for no reactions can be obtained from symmetry (so the reactions should be in the same direction) and from moment equilibrium (so the reactions should be …
