Terzaghi’s ultimate bearing capacity equation for a strip footing on c-phi soil is given by:
Aq_u = c * Nc + q * Nq + 0.5 * gamma * B * Ngamma
Bq_u = c * Nc + q * Nq + 0.3 * gamma * B * Ngamma
Cq_u = 1.3 * c * Nc + q * Nq + 0.4 * gamma * B * Ngamma
Dq_u = 1.2 * c * Nc + q * Nq + 0.5 * gamma * B * Ngamma
