As said ‘e-deck' system is used for the slabs, which is the main structural (horizontal) component of the building (slab thickness up to 30 cm). Can a Circle of the Stars Druid roll a natural d3 (or other odd-sided die) to bias their Cosmic Omen roll? A PT concrete podium slab provides better crack control due to the pre-compression applied to the structure. @Menna - And as hazzey has said, "it will be impossible to estimate any thicknesses". This Hollow-core level can act as a Podium Slab, ... Hollow-core Transfer Level or Podium Slab Typical Cast-in-place or ICF Foundation Walls Traditional Timber or ICF Construction Single Family Podium Construction Precast Solutions . We might do enough calculation on here to design a simply supported beam, but not for complicated loads of varying types over a large area. Realizing no one at my school does quite what I want to do. Absence of evidence is not evidence of absence: What does Bayesian probability have to say about it? I'm not an engineer, though I can say with some confidence that slab thickness has little to do with the overall height of the building.
