2. Design the dimension of a square footing to carry a column load 1800 kN. The base of the footing will be placed at 1.5 m below the level of the surrounding ground surface and a minimum factor of safety 2.5 is required. Soil around the footing is clayey sand with cohesion of 20 kN/m, and friction angle of 30°. The unit weight of soil above the water table is 18.5 kN/m and the unit weight below the water table is 20.0 kN/m. The water table is at the footing base level 2.
