Post Tensioning-Deferred Engineering/Detailing
Post Tensioning-Deferred Engineering/Detailing
(OP)
Our firm is going to be involved in several condominium type structures, which have a good chance of being post-tensioned flat plate construction. I am wondering how far you typically take the engineering/detailing of such structures, as opposed to deferring same to the post-ten supplier. For example, for the banded tendons, do you typically show tendon direction, force after losses, and drape? Do you design/detail shear reinforcing in the slab? I don't want to be too far out of line either way compared to what the engineering community at large is doing.

I have worked for a PT supplier and I am currently work in a consulting firm. What you provide on the contract documents depends greatly on your geographic location. For example, for any permits to be pulled for construction in Florida, a building with pt floors need to have a "complete design" which many times means that the EOR has placed a large amount of PT on the drawings with minimum steel and sent it out the door, with the knowledge that the contractor will have the PT supplier re-design the slab more efficiently. Others will issue the drawings with the post-tensioning as a pre-engineered specification, as dik had indicated. Thirdly, you can design and detail the slab yourself indicating banded/uniform direction and force, drapes, mild-steel reinforcement etc. In this case all the supllier will do is provide tendon support drawings, tendon layout and endviews.
