a) A 2 mx 2 m square footing is subjected to an axial load of 600 kN and a bending moment of 180 kNm as appears in Figure 2. The footing is located at 1.2 m deep in a cohesionless soil that has a friction angle of 35° and a saturated unit weight of 18.4 kN/m³. The water table is 2.7 m below the soil surface. Calculate the following, (i) Calculate the eccentricity of the load, (ii) Calculate and draw the soil contact pressure beneath the footing, (iii) Determine the factor of safety of the footing against the bearing capacity (use the general Meyerhof, bearing capacity equation). Assume the soil above water table is saturated. = 600 kN at 18.4 kN/m³ 1.2 m c'= 0 kPa, '= 35° 1.5 m DI. 2m M = 180 kNm Figure 2
