A strip footing 2 m in width, with its base at a depth of 1.5 m below ground surface, rests on a saturated clay soil with γsat = 20 kN/m3; cu = 40 kN/m2; ϕu = 0; c’ = 10 kN/m2; and ϕ’ = 20°. The natural water table is at 1 m depth below ground level. As per IS: 6403 – 1981, the ultimate bearing capacity of this footing will be (taking the relevant Nc as 5.14)
