Example $04$

A square footing is $22m$ with a $0\mathrm{.}40\mathrm{.}4m$ square column. It is loaded as shown in the figure. Drained shear strength parameters of soil are ${}^{\text{'}}=38$ and $c^{\text{'}}=0$kPa. The footing depth is $1m$; the soil unit weight $g=17k\frac{N}{m^3}.$ What is the allowable soil pressure, if FOS is $3\mathrm{.}0$ using:

i$.$ Neyerhof's equation

ii$.$ Vesic's equation
