Geotechnical Bearing Capacity Calculator

Formula Used

q₍ult₎ = cNc + γDfNq + 0.5γBNγ

This calculator estimates the ultimate bearing capacity of a shallow strip footing using a simplified Terzaghi bearing capacity equation.

• c: soil cohesion
• γ: soil unit weight
• D_f: foundation depth
• B: footing width
• N_c, N_q, N_γ: bearing capacity factors
