Pole barn column

[JStructsteel]

Looking at a pole barn, and trying to decide a Ky factor for my column. I know its not fixed, and i know its not free. Somewhere in between? Ky 1.6 keeps the column in check. Whats your opinions?

I was just guessing at the spacing based on what I've seen built locally.

For our structure foundations here in Wyoming, we neglect the lateral restraint of the top 5' of soil to account for the possible effects of frost loosening the soil around the foundation.
