Slab Pre-Dimensioning


h = slab thickness
ln = clear span of slab in the direction examined

  • TBDY 2018 guides TS 500 for 7.11.2 thickness of flat slab. The following explanations are included in TS 500 11.4.2 design principles section:

  1. The thickness of flat slabs operating in two directions can not be less than the following value.
    For floors without beams, h ≥ l n / 30 and h ≥ 180 mm

  2. Flat slab thickness should be selected in a way that it does not require punching reinforcement.

  • Selected slab thickness: 27 cm
