Effect of Concrete Strength and Slab Thickness on Floor ...

Most designers calculate the required thickness of a floor based on the flexural strength of the concrete. Flexural strength is estimated by the modulus of rupture, which is assumed to vary with the square root of the compressive strength. In the equation that relates design slab thickness and modulus of rupture, the thickness term is squared. Thus the thickness varies with the square root of ...
