Formula Reference
Bearing Capacity: qult = cNcscdcic + qNqsqdqiq + 0.5γB'Nγsγdγiγ
Net Ultimate: qult,net = qult,gross - q
Allowable: qallow = qult / FS
Eccentricity: ex = |My| / P, ey = |Mx| / P
Effective Dimensions: B' = B - 2ex, L' = L - 2ey
Corner Pressure: qcorner = P/(BL) ± 6Mx/(BL²) ± 6My/(LB²)
Sliding: FS = (P tan δ + ca A) / H
