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 (f_ck) in MPa.

• Select the grade of steel (f_y) 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 L_eff 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
