Drilled Pier Reinforcement Design
Drilled Pier Reinforcement Design
(OP)
I'm trying to find out the best way to determine the required amount of steel for a circular drilled pier foundation. I was wondering if anyone has a suggestion for a reference for determining an effective "d" for the reinforcement placed in various circular patterns.

Is it promarily axial load or is there more significant bending with the piers used for lateral load resistance such as on a hillside foundation? I've found that with the latter, PCA sells a software that allows good refinement of steel cages.

For years, most of the drilled piers we designed (in South Texas) were reinforced with approximately 0.75% reinforcing (0.0075 x Gross Area of Pier)as a minimum and with a second criteria provided by the geotechnical engineer that attempted to deal with the potential uplift of the pier in expansive clay situations. This was usually a formula involving the pier circumference.
