Does compression/tension change anything with static loads?

Your design standard would address your concerns.

I'm a college student and the only thing I know is that the load is static and that the tensile stress is around 90% of the compression stress. The question is which will cause a failure first. I suppose that it doesn't matter with static load, but from experience, if you weld a vertical pillar to the ground and apply enough force on it horizontally, which side will give out first and is there a difference at all?

If the materials of construction is carbon steel, the allowable tensile stress and compressive stress are considered to be equal. If the material of construction is cast iron or concrete, the allowable unit stress is not and the design must take those factors into consideration.

Thank you for your time and a satisfactory answer.
