Title: RE: Caisson Design Program

Mike:

A great deal of work has been done in this subject area, both for the offshore oil industry and for the Texas Department of Transportation (TXDOT).  Virtually all of the early (1970s) work was done at the University of Texas in Austin by Hudson Matlock and Lyman Reese.  Since then, I believe that the work has spread to other local institutions, such as Texas A&M University and the University of Houston.  For the most part, the resulting programs follow the theory of beams broken into discrete elements and bearing on inelastic soil springs.  Of course, it takes a good deal of soil testing and quite a bit of luck to get those nonlinear springs anywhere near to "correct"!;^>

Since your interest is concrete caissons (in Texas, we call them drilled piers or drilled shafts), rather than steel pipe piles, I suggest that you start your search at TXDOT in Austin and/or the Texas Transportation Institute (TTI) at College Station.  Either way, this should result in public domain (probably free) software.

Try http://www.dot.state.tx.us/ or http://tti.tamu.edu/

Good hunting!  If you find a really great program, please let all of us know!

Hello,

Are ther any good caisson design programs that handle moment in addition
to axial load?
