Problem $2$: for group $7$

Find the required depth, width and steel reinforcement for the Reinforced Concrete footing shown in the figure below. The footing is for a Reinforced concrete wall of width $"$a$".$

D I.

The bottom of the footing is at a depth $"$b$"$ below the grade.

The service load carried by the footing per linear meter is composed of Dead load including the wall weight $"$D$"$ and Live Load $"$L$".$

Values of $"$a$","$b$","$D$"$ and $"$L$"$ are specified in the Table below.

The value of the allowable bearing capacity of the soil is also given in the table below.

Consider:

Soil weight per unit volume: $5k\frac{N}{m^3}.$

$[[$Group$,$a$($mm$),$b$($m$),$D$($KN$/$m$),$L$($kN$/$m$^(\text{'})),$Bearing Capacity $($kN$/$m$^(2))],$
