Post Tensioned Slabs - Max precompression
Post Tensioned Slabs - Max precompression
(OP)
ACI 318 18.12.4 sets the lower limit of precompression force in a post tensioned slab at 125 psi, but I don't see any mention of the upper limit anywhere in the code. I read somewhere that the recommended maximum precompression force is 300 psi for slabs. Does anyone know if this is true and if it only a recommeded value as opposed to something that needs to be followed strictly.

Higher moment required to overcome the compressive stress and start cracking the concrete (servicability against corrosion and water retention structures).
Lower deflections available.
