Openings in flat plate PT
Openings in flat plate PT
(OP)
Does anyone know where I can find guidelines on openings in flat plate PT construction? I can find information for mild reinforced flat plate all over the place, but can't find any guidance on PT flat plate.

Detailing of additional mild steel reinforcing and how the interrupted tendons are displaced around the opening will be critical for crack control.

That's specific to mild reinforced two-way slabs. I'm trying to find something that addresses PT. Even if I could find something that says the mild reinforced guidelines are applicable to PT....... that would be helpful.
Slick-
I did come across that one, but it looked like it was for mild reinforced slabs.

I also remember that the PTI manual has some details for slab openings. Perhaps you can find this manual and let us know what you find.

The concept is exactly the same as for an RC flat plate. The only problem is that ACI says RC and PT slabs/beams are different. But that is only because they are about 50 years behind and they try to make special rules for every possible different situation!
Use your engineering judgement to apply the RC flat plate rules to PT flat plates.
