Bearing Capacity Factors Calculator (Nc, Nq, Nγ)
The three classical factors for any friction angle — exam and design staple.
Memorize the anchors: φ=0 → 5.14/1/0; φ=30 → 30/18/22; φ=40 → 75/64/109. Factors EXPLODE exponentially with φ — why a degree or two of lab error matters so much.
Formula
Bearing Capacity Factors Calculator (Nc, Nq, Nγ) is a free bearing capacity factors for geotechnical engineers and foundation designers — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Bearing Capacity Factors Calculator (Nc, Nq, Nγ)
The three classical factors for any friction angle — exam and design staple. The calculation implements N_q = e^(π·tanφ)·tan²(45+φ/2); N_c = (N_q−1)cotφ; N_γ = 2(N_q+1)tanφ (Reissner/Prandtl/Vesić; IS 6403 tables). Memorize the anchors: φ=0 → 5.14/1/0; φ=30 → 30/18/22; φ=40 → 75/64/109. Factors EXPLODE exponentially with φ — why a degree or two of lab error matters so much.
