A footing of size 2mx 2m transferring a pressure of 200 kN/m², is placed at a depth of 1.5 m below the ground as shown in the figure (not drawn to the scale). The clay stratum is normally consolidated. The clay has specific gravity of 2.65 and compression index of 0.3. 1.5 m 1m 1.5 m 200 kN/m² Silty sand Clay Ya = 15kN/m³ GWT = 18 kN/m³ Y sat Y sat = 17 kN/m³ 0.5 m Dense sand Considering 2:1 (vertical to horizontal) method of load distribution and Y = 10kN/m³, the primary consolida- tion settlement (in mm, round off to two decimal places) of the clay stratum is

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.
