Terzaghi Bearing Capacity

Calculates ultimate and allowable bearing capacity of shallow foundations using Terzaghi's (1943) classical equation: qu = c*Nc*sc + q*Nq + 0.5*gamma*B*sg*Ngamma, with shape factors for strip, square, and circular footings. Includes water table correction for overburden and effective unit weight, and bearing capacity factors Nc, Nq from analytical expressions with Ngamma interpolated from standard tables.
