WebRankine’s theory for finding buckling load on strut is used to calculate buckling load in the columns of short, average and large length. The column is decided to be short, medium or long based on the l/k ratio. The derivation of Rankine’s formula starts from the statement. 1/P_R =1/P_E +1/P_c.

In practice the most important buckling load is the first, corresponding to n 1, since this will be the first of the loads reached as the applied load P is increased from zero; this is called the critical buckling load: 2 L Pc EI (7.5.10) with associated deflection

WebAs Euler buckling theory tells us, when the elastic critical buckling load is reached, the member (or indeed an entire structure) will fail in a buckling ‘mode’ or shape which is unbounded - i.e. the element (or structure) can displace indefinitely and hence has zero stiffness.
