Question

A circular footing is to carry the load given. The foundation shall be embedded at a depth of 2.2 m below ground level (GL). The groundwater table was observed 2 m below BOF. Using the following soil data (dense sand):

γ_soil = 18 kN/m³
γ_sub = 10 kN/m³
c = 12 kPa
N_c = 17.69
N_q = 7.44
N_γ = 3.64
FS = 3.0

If the total service load to be carried concentrically is 520 kN, what should be the radius of the circular footing (m)?

the final ans is 0.91
