Prestressed and Post Tensioned Concrete Design
Prestressed and Post Tensioned Concrete Design
(OP)
My background is in structural steel design and construction management. Would appreciate suggestions for a good PT software and/or design book(s)with examples of prestressed and post tensioned structures, that include slabs on grade. I am aware of what PTI and ACI have. Any other recommendations? Thanks.

Beam from J&A is another Pre-stressed software. I don't know of any specifically for post-tensioning.
RE: Prestressed and Post Tensioned Concrete Design
Slabs on grade generally follow the rules of normal post tensioned design. Imagine the bearing stress is a UDL with the columns coming down on the slab acting as supports. Depending on the loads being transferred and the soil conditions it might be possible to run the tendons straight with no profile. Otherwise the profile is the mirror image of what one would expect with a suspended slab.
I have never heard of a pre-stressed slab on grade, there would be a lot of issues with joints and installation.
