Numerical Evaluation of Terzaghi's Nγ

Numerical limit analysis solutions for the bearing capacity factor Nγ

“…6) and found the most critical one using a graphical method. More than three decades later Kumbhojkar (1993) used a similar approach, but derived an analytical expression for N c and compared his estimates with those of Terzaghi. He found large differences for high friction angles and attributed this discrepancy to the approximate nature of the graphical method used by Terzaghi.…”

Bearing Capacity and Settlement of Footings in Unsaturated Sand

“…Several investigators provided bearing capacity factors for cohesion, N c ; surcharge, N q and unit weight, N γ ([1], [2], and [28]). The values for bearing capacity factors of N c and N q provided by various investigators are approximately the same.…”

“…For this reason, the bearing capacity factors, N c and N q originally proposed by Terzaghi [1] were used in the analysis. The values N γ suggested by [28] have been widely used in recent years. For this reason, these values are used in this study.…”

A simple method for the prediction of modulus of elasticity for unsaturated sandy soils

“…where q ult = ultimate bearing capacity, c = effective cohesion, φ = effective internal friction angle, ψ = fitting parameter, B = width of footing, γ = soil unit weight, N c and N γ = bearing capacity factors from Terzaghi (1943) and Kumbhokjar (1993) respectively and ξ c , ξ γ = shape factors from Vesić (1973).…”
