From classic elastic column buckling theory ( [70,123], see also Section 10.3.2), the Euler buckling load is the compressive axial force necessary to cause lateral instability of a vertical, weightless column. The formula for the Euler buckling load is 10. (10.6)

NettetEuler’s Theory. The Euler’s theory states that the stress in the column due to direct loads is small compared to the stress due to buckling failure.Based on this statement, a formula derived to compute the critical buckling load of column. So, the equation is based on bending stress and neglects direct stress due to direct loads on the column.
