(OP)
Gentlemen,
Can anyone please advise concerning the design of ring foundations for silos using piles? Looking for reference material and examples. Thanks.

RE: Foundation Design For Silos
well i´ve designed two or three silos some time ago. i used the ACI code and a book of juan Ravennet that is in spanish. its quite simple but you have to take into account that depending on the height to width ratio(>2.5) the stresses in the walls or the base are different and you have overpressure effects when the material is taken from the silo.
i could help you if you want. just let me know

I want to put the tower on a ring foundation supported by caissons. I anticipate the ring to be 7 ft wide by 3'-6" deep on 4 ft diameter caissons spaced at 7'-0" c/c.
I need help in checking the design of the ring.
Thanks.

A mat needs to be wide to allow sufficient lever arm for the outer caissons to resist uplift forces.
A mat needs to be thick to minimize deflection under dead and live loading so that caissons at the perimeter of the mat are loaded essentially equally as those directly under the silo.

F(pile) = 4M/ND
Where: M = overturning moment
N = number of piles (at least 12 or the formula is not accurate)
D = diameter of circle through the centerline of the piles.

No silo/tower wall designs are required. They will be reinforced concrete by the tower contractor.
I do have Bowles' textbook but you cannot utilize Chapter 9 very well unless you have his ring foundation program.
If anyone has this old fortran program please advise.
Thanks.
