Pole buckling due to own weight

[Anisotropos]

In the structural design of a long and slender metallic pole (of tubular section) it is necessary to consider the buckling due to own weight? ¿How?

 

[GregLocock]

It is a standard result. Solve it by Euler's method.The solution is transcendental.

Yes, it is a genuine failure mode, for some materials/systems.

In practice it will be incredibly sensitive to the rigidity of the footing, and the presence of side loads and imperfections.

is a good enough intro
