Column size $(300 \times 450)$ mm

$P = 1000KN \\ Pu = 1.5 \times 1000 = 1500 KN \\ SBC = 190 KN/m^2$

Area of footing $(A_f)=\dfrac {P+10\% \text {extra assel fwt,}}{SBC}\\ =\dfrac {1000+\frac{10}{100}\times 1000}{190}\\ = A_f=5.81 m^2$

enter image description here

$C_x=\dfrac {B-0.3}2 ;C_y =\dfrac {L-0.45}2$ $ Now, C_x=C_y \\ \dfrac {B-0.3}2=\dfrac …
