Hey Customer,

well this is a good question. It is possible to design a post-tensioned member such that no tensile stresses exist under service loading. However, in the absence of information to the contrary, it is always appropriate to assume that the underside of a slab is in tension, and therefore, cracking is likely to occur. Please feel free to reach out any time, if you need additional information.

Kind Regards
Jerrod
