A footing is embedded to a site of sandy clay at a depth of 1.6m below the natural grade line (NGL). The soil has the following properties: cohesion is 10kPa, angle of internal friction is 35˚, the specific gravity of the soil solids is 2.75, void ratio is 0.55 and the water content is 5%. The water table is at a great depth. Consider Terzaghi's general shear failure and a factor of safety 3.5. For angle of internal friction of 35˚, the bearing capacity factors are Nc= 57.75, Nq = 41.44, and Ny = 45.41. S=1.20m
a. What will be the allowable load, in kN, for a 1.2m square footing?
b. What will be the allowable load, in kN, for a 1.20 m diameter circular footing?
c. What will be the allowable load for a 1.2m wide wall footing per meter length?
