This paper contains recommendations concerning designing post-tensioned slabs published in technical literature, i.e., span-depth ratio and maximum span. To reflect these recommendations and show new possibilities, a few selected realizations have been described. The described examplesinclude one of the largest solid post-tensioned slab with dimensions of 17.65 × 19.69m and thickness of 350mm designed by the authors. Additionally, the ways of improvement of post-tensioned slabs’ effectiveness were proposed.
