Design of Reinforced Concrete Slab
PROCEDURE
Enter the larger(Ly) and smaller(Lx) dimensions of slab in mm.
If Ly/Lx is greater than 2, then the slab will be designed as a one way slab.
Select the grade of concrete (fck) in MPa.
Select the grade of steel (fy) in MPa.
In the next level, select the depth of slab (D) in mm
Calculate the effective depth of slab in m by deducting the cover.
Enter the span of slab L in m.
Enter the width of support in m.
Calculate Leff in m. After three incorrect attempts, correct formula and value will be displayed.
Enter the load on slab (w)
Calculate the load in KN/m (W). After three incorrect attempts, correct formula and value will be displayed.
Calculate the factored load (Wu).
In the next step, calculate the bending moment (Mu) in Nmm, considering a simply supported span. After three incorrect attempts, correct formula and value will be displayed.
Calculate Area of steel (Ast) in mm2
Minimum Ast will be calculated and compared with our calculated Ast. The maximum value will be considered.
Select the bar diameter in mm.
Spacing will be calculated in mm
