3. To investigate the influence of different material The initial theory of the buckling of columns was worked out by Euler in 1757, a nice example of a theory preceding the application, the application mainly being for the later “invented” metal and concrete columns in modern structures. 2020-12-28 Euler Column Buckling (1744) Valid for all materials !

Our use of Euler's buckling formula here is NOT intended for actual design work, but ONLY as a. The Euler formula for the elastic critical buckling load of a slender column is the earliest engineering design formula that is still in use to- day.

The theory given by Euler is based on the assumption that the column fails due to the buckling load only. However, this is not the case. There is crushing load acting on the column too. The failure could be due to crushing load or a combination of the crushing load and the buckling load. Once buckling initiates, the instability can lead to failure of the column, because the eccentric force acts as a moment causing greater stresses and deflections due to the combination of the bending and axial forces.

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.
