Directions: Show your solutions explicitly, I.e., do not just write the final answer. Always simplify and box your final answer. 1. A wall footing is to be constructed on a clay soll 1.4 below the ground. The footing is to support a wall that imposes a load of 130 kN per meter of wall length. Considering general shear failure, determine the following: 130 kN/m 4m a. Footing width if the factor of safety is 3. b. Ultimate bearing capacity if B = 0.95 m. c. New factor of safety. Y = 17.92 kN/m² c = 14.5 kPa $ -30° 2. A square footing shown has a dimension of 1.5 mx 1.5 m and has its bottom 2 m below the ground surface. The groundwater table is located at a depth of 3 m below the ground surface. Assume a general shear failure. Determine the following: L 2 m y = 16 kN/m³ c = 14.5 kPa = 28° 3 m 1.5 m Ysa1 = 18.5 kN/m³ a. Ultimate bearing capacity of the soll beneath the footing (in kPa). b. Allowable bearing capacity if it has a factor of safety of 3 (in kPa). C. Allowable load that the…
