Been doing a little research on the design of Post-Tension foundations and came across two excellent information sources
Post Tensioning Institute

VSL out of Baltimore, MD.

PTI has pretty much set the standards for PT Design and installation. They are even called out as one of the main references in the International Building Codes.
The VSL site has a number of very interesting engineering design documents, as well as others regarding PT foundations. They deal mostly with large scale projects but the documents are based around PT design for all structures. Although they are heavy into engineering principles there is a lot to be obtained on a general level for those not interested in breaking out the slide rule (oops, just gave away my age  ).
