DESIGN OF AXIALLY LOADED COLUMNS

σe = Euler buckling stress given by (1a) 2 π2E λ η = a parameter allowing for the effect of lack of straightness and eccentricity of loading. λ = Slenderness ratio given by (λ/r) In the deviation of the above formula, the imperfection factor η was based on (2) r2 y⋅∆ η=

Lateral torsional buckling and slenderness

Euler (flexural) buckling of a strut in that it defines a buckling load. Euler bucking defines the axial compression that will cause a strut to fail in elastic flexural buckling compared with the elastic critical moment that defines the moment that will result in failure due to elastic lateral torsional buckling of a beam. The Elastic critical ...
