FOr my 40x60' barn I used Treated 6x6" poles that I sunk 30" deep into the ground by just using a post hole digger. At the bottom of the holes I placed a round concrete footer that was about 16" in DIamet and 4" thick. On the outside edge of the poles I nailed a 4"x6" piece of treated lumber about 12" from the bottom to give it an edge that would have to displace ground if it were to try and heave. NOt sure if that made any difference, but after 3 years there has been no movement yet. I live near St. Louis MO so aour winters usually aren't too severe, but we do experience about 6 weeks of at or below freezeing weather.
