The Euler equation overestimates the column buckling capacity, increasingly as column slenderness drops below 200.
EK407
Euler equation has validity only with perfectly straight columns, free of residual stresses, loaded at the centre of gravity and knife-edge supports.
EK225
The Euler buckling theory makes no allowance for: Homogeneity of column material. Isotropy of column material. Variation of Young’s modulus and elastic-plastic behaviour of column material. Loading not axial. Residual […]
