Caisson Foundation Design, Steel Requirements
(OP)
I am designing a high-ecentricity caisson foundation two support a transmission line pole and am looking for some recommendations on the vertical steel requirements. Can anyone point me in the right direction. I can't find anything in the ACI that specifies a steel area for this type of foundation. I will treat it like a beam. I found one formula in a company standard that says the required steel area is As = (3.33 x Mult x 12)/ (fy x Ds)
Thanks!

The reference for the above quote is Drilled Shafts: Construction Procedures and Design Methods, Publication No. FHWA-IF-99-025, pg. 363. It goes on to say that the above criterio can be used often because drilled shafts are typically designed with large diameters in order to develop sufficient side friction and end bearing in both soil and soft rock.
