A rectangular footing (1.5m x 2.0m) founded on sand.
The footing was designed using a factor of safety equal to 3.0 and
a design load of 1800 kN. When constructed the contactor displaced
the center of the column by 0.26 m away from the center of footing
in the long direction and the column was inclined 8o from the
vertical. Determine The factor of safety against maximum contact

Question 3 (70) Design an isolated rectangular footing of dimension 4m x 5m. The gross pressure acting at the base of the footing is 150 kN/m2. Choose the depth of foundation such that the factor of safety is exactly 3 against shear failure. Also check against the permissible settlement (75mm) to ensure that the design is safe from the settlement criterion too. If the design is not safe against settlement criterion, then choose the proper...
