looking for a good design reference text on pier design

[fenderbassman]

I have been looking on the net and in the libraries for a well-written, understandable text with design examples of concrete drilled pier design, to no avail. I am specifically looking for help in design of vertical steel to resist lateral loading. Does anyone have a favorite text for this subject?

fenderbassman,

Usually, the geotechnical engineer will prepare a lateral response analysis for various pile sizes and embedments. This will require the structure's design loads (vertical , lateral and moment) at the pier caps/columns as input.

The analysis may go through several iterations with the structural engineer, to account for the effects of resteel in the response.

In the end, it all comes down to the predicted shear and moment in the drilled pier. Designing steel to accomodate these loads is usually straightforward.

See FHWA IF-99-025 "Drilled Shafts - Construction Procedures and Design Methods" available here:

Note that there is also an errata document.

You might also want to check out M.J. Tomlinson's book on Pile Design and Construction (Viewpoint Press). He is, in my opinion, the best at piled foundations - and his book has numerous real problems with solutions.

You may want to take a look at the following:

"Drilled Pier Foundations" by Woodward, Gardner and Greer, McGraw-Hill, 1972

Also, the paper "Analysis and Design of Laterally Loaded Piles and Caisson in a Layered Soil System" by Naik and Peyrot, ASCE

I found a book by Petros P Xanthakos called " Bridge Substructure and Foundation Design" to be very thorough.. Rittz

I would use Brom's method to predict the soil-pier behaviour under lateral loads, this can be easily programmed into a spreadsheet and will enable you to determine the maximum moment in the pier.

To ensure the pier is structurally adequate, I would use concrete design principles to calculate the moment capacity for the pier, this should also be easily programmed into a spreadsheet.

Keep your reinforcement above 1% of the total cross-sectional area.

I would also like to recommend Tomilson's textbook on Pile Design.
