simply supported one$-$way solid slab, span of $4\mathrm{.}0$ m the thickness of the slab is $200$ mm and

the slab can bear a ultimate load of $12K\frac{N}{m^2}$ Required:

$1\backslash$We verify the thickness of the slab according to the requirements of the American code.

$\frac{2}{\frac{?}{?}}$ If the concrete is resistant to shear $V=111KN,$ check the shear in the slab.

$3\backslash$Verify the moment$-$resistant thickness dm$.$
