Drilled Pier Design
(OP)
I am looking for some useful references or examples on design of drilled piers. Any help in this regard would be greatly appreciated. Thanks in advance.

If you have any specific questions, I will try to answer them.

Thank you for your response. I was able to find a copy of ACI 336 and started reading through it. I will even checkout the CRSI manual.

To be specific, I am looking for structural design of drilled piers. But, I am even reading though the geotechnical aspects to get a better understanding. But, I couldn't find a good example on structural design of drilled piers.

The usual configuration of bars is axial (vertical) about the perimeter.
It will also model cracked vs. uncracked EI.

We commonly reinforce piers for uplift resistance based on expansive soil action.
RE: Drilled Pier Design
Calculated uplift and/or moment are a different ball game.
RE: Drilled Pier Design
However, reinforcing should be taken down to the pint where the uplift forces can be transferred to the soil. Sometimes this is the entire length of the pier.
Also remember that uplift can occur at piers supporting shear walls or x-bracing.

Other than that is is generally designed as a short column.

I've noted the following paper a few times before, but it is a very interesting and informative look at the problem.
You might find the paper "Analysis and Design of Laterally Loaded Piles and Caissons in a Layered Soil System", by T.R. Naik and A.H. Peyrot. It was published in the 1970's in an ASCE journal. The paper is based on a modificaiton of Broms' method and it has a very practical approach with a good example problem and a pretty extensive list of references.
Also, "Drilled Pier Foundations" by Woodward, Gardner and Greer, McGraw-Hill, 1972
