As per IS 6403, the net ultimate bearing capacity of a shallow strip footing (Terzaghi) on c-phi soil is:
Choose the correct answer
q_nu = c Nc + q Nq + 0.5 gamma B Ngamma
q_nu = c Nc only
q_nu = q Nq + 0.5 gamma B Ngamma
q_nu = q Nq - c Nc
Correct Answer
A. q_nu = c Nc + q Nq + 0.5 gamma B Ngamma

Terzaghi (strip footing): q_u = c Nc + q Nq + 0.5 gamma B Ngamma, where q = overburden pressure = gamma x Df, Nc, Nq, Ngamma = bearing capacity factors (function of phi). Net: q_nu = q_u - q. Allowable: q_a = q_nu / FOS + q (FOS = 2.5 to 3). Shape factors applied for rectangular/circular footings.
