A concrete foundation wall is to be constructed for 210’x240’ building that total loading of 3x105 kN. The clay specific weight Y = 115 Ibf/ft3 (p = 1840 kg/m3), and clay has an average compressive strength of 30 kpa. Determine the depth of foundation wall by using safety factor 2, bearing capacity factor 6 in order to confirm the constructability of that foundation wall.
