A rigid foundation is subjected to a vertical column load, $P=355kN,$ as shown in Figure $1.$ Given: $B=2m$;$L=3m$;$D_f=1\mathrm{.}5m$;$H=4m$;$E_s=13,500k\frac{N}{m^2}$; and ${}_s=0\mathrm{.}4.$

Estimate the elastic settlement due to the net applied pressure, $,$ at the center of the foundation.

Hints:

$=\frac{P}{\text{A}\text{r}\text{e}\text{a}}=\frac{P}{BL}$

$B^{\text{'}}=\frac{B}{2}$ for the center $of$ the foundation

$B^{\text{'}}=B$ for the corner
