As I have been working through examples of construction projects, I've noticed that in nearly every case of a structural column (sample size considers only homogeneous material columns, no composite structures) the materials chosen to construct the beam will yield before the beam design chosen will experience Euler buckling. I may not be considering all use cases but is it easier (or more likely, safer) to design for yield failure modes than for buckling failure modes?
Perhaps manufacturing tolerances on mass produced steel beams are sloppy enough compared to material composition that it requires a larger Factor of Safety?
