**SAFE** reports Area of reinforcement in unit lentgh^{2}/length (mm^{2}/m, cm^{2}/m, and in^{2}/ft).

For calculating Number of bars@spacing, do the following:

Select Bar Diameter, multiply its area with strip width & divide Strip width by required Area of steel.

Example:

Assume we get strip Area of Reinf. from SAFE, A_{s} = 323 mm^{2 }/m

suppose T10 mm diameter bar, A_{b} = 78.5 mm^{2}

Check the strip width from SAFE, Assume, W_{s} = 1 m

Spacing can be calculated in this way, S = A_{b} x W_{s}/A_{s}

Therefore, S = 78.5×1/323 = 0.243 m

Provide T10@225mm Spacing,

As = 78.5×1/0.225 = 348.88 mm^{2}/m

Hello, I want to ask about the area of footing:

How could I know whether the area of footing is enough or not using SAFE
