Question : 109 of 200

Marks: +1, -0

A square footing for a column carries a total Load (including the self-weight of footing) of 1760 KN. The safe bearing capacity of soil is 200

\kN\/\m^2

. Using M 20 grade concrete and Fe415 steel, the area of footing (rounded to the nearest integer) will be

Solution:

Total load = 1750 kN, Safe bearing capacity = 200

\kN\/\m^2

\A_{\f}={{ \text "Total load" }}/{{ \text "Safe bearing capacity" }}

\A_{\f}={1760}/{200}=8.8 {\m}^{2} ≈9 {\m}^{2}
