7. A reinforced concrete square footing supports a 400mm x 400mm square column carrying a total dead load of 740kN and a total live load of 1120kN. The footing dimension is 3m x 3m and is supported by 9 piles 1m apart on a 3x3 formation. The effective depth of the footing is 700mm. Take f’C = 28MPa for concrete and fy = 415MPa for steel.
a. Determine the factored load on each pile.
b. Determine the nominal wide beam shear stress to be resisted by the footing.
c. Determine the nominal punching shear stress to be resisted by the footing. d. Determine the factored moment to be resisted by the footing.
