The present study demonstrates the computational bearing capacity estimation of conical footings resting on sand deposits. The parameters varied in this study were (i) embedment ratio, Df/B (where: Df = embedment depth of footing and B = diameter of footing) (0, 0.25, 0.5, 0.75, and 1), (ii) apex angle of conical footing, β (30°, 60°, 90°, 120°, 150°, and 180°), and (iii) friction angle of sand, ϕ ( 25°, 30°, 35°, 40°, and 45°). The Mohr–Coulomb failure criterion and the non-associated flow rule (ψ < ϕ) were considered to be applicable to the soil. The results are expressed in terms of bearing capacity ratio (BCR) and settlement reduction factor (SRF). It is observed that for ϕ < 30°, the magnitude of bearing capacity decreases continuously with an increase in β from 30 to 180°. Whereas, for ϕ > 30°, the minimum bearing load capacity is found to occur generally between β = 120° and β = 150°. In all the cases, it is noticed that the bearing capacity becomes maximum for β = 30°. The bearing capacity values obtained are found comparable to those published in the literature.
