A rectangular footing (4.31 x 4.07 m.) is placed 1.2 m. below the ground surface. The soil arrangement is composed of sand (ground) for the first 5.52 meters and followed by clay for the next 5.91 meters. The force acting on the footing is 10,163 kN. Determine the settlement of the consolidating layer in mm. Assume a 2V:1H pressure diagram. Unit weight of sand = 16.6 kN/m3. Clay has the following properties: Unit weight = 18 kN/m3, Void ratio = 82, Liquid limit = 44. Round off to two decimal places.

Q#4: Plate load test performed on a uniform deposit of sand and the following observations were recorded. The size of the plate was 45cm x 45cm.

For the embedded strip footing (infinitely long in the out-of-plane direction) shown below, the maximum vertical pressure that the soil can bear before failure is 100 kPa (i.e., qmax should not exceed 100 kPa). What is the maximum overall eccentricity of the foundation in mm before failure? (answer tolerance = 2%). Consider γconcrete = 25 kN/m3, γsoil = 18 kN/m3 and assume that the width of the embedded column is negligible, and the entire top of the foundation is covered with soil. Hint: for a strip footing, the calculations should be conducted assuming a 1-m long footing in the out-of-plane direction.
