Using Enercalc for Pole embedded in soil, gives restraining force if pole is restained with cocnrete floor etc. How to manually cross check this force?

dgkhan,
Would diameter of pole x Area of contact w/ concrete x design compressive strength of concrete do it?
d x A x f'c
You may need to use a reduction factor for f'c (typically 0.85) and/or an arching effect multipiler for d (typically 2-3).
Hope this helps.

Force at the concrete level should be the sum of your lateral P force at the top of the pole plus your passive pressure against the pole and footing under the slab level. 字串5
Remember, for a pole barn, 2X the IBC table values of passive pressure are allowed since more deflection is permissable. Mike McCann
