To secure formwork into compacted soil the contractor is using a 2x4 base plate and using #5 rebar driven 16" into the ground to anchor the base plate.
The loading on this will be the horizontal load from wind forces and horizontal forces produced by the uncured concrete and the vertical forces generated by wind.
To determine how much force can be resisted by the rebar anchor, I'm assuming for shear, as for a simplified procedure similar to that of soldier piles, the soil compressive strength would control the resistance to shear.
Not sure how I would compute pullout resistance of the rebar in the compacted soil?
I have searched quite a few references including AASHTO but with little luck. Hoping someone can steer me in the right direction.
Thanks.
