“…This same issue was raised by (Ganesh et al, 2016); according to these authors, this error might be due to the fact that the effect of D f /B was not taken into consideration for computing the RF in the presence of eccentric loads.…”

“…Moreover, for the case where D f /B=0, with vertical and eccentric loading conditions, the RF proposed by (Patra et al, 2012) clearly overestimates the average ultimate bearing capacity, as will be explained in detail below. Ganesh et al, (2016) proposed an empirical formula for the RF. According to the authors, this was developed after analysing a series of laboratory model test results available in the literature.…”

“…This formula was based on an approximate solution, which had used superposition, and the solution of (Prandtl, 1920). According to (Terzaghi, 1943) and (Prandtl, 1920), different theories are usable for the computation of the ultimate bearing capacity of shallow foundations subjected to central vertical loads (Meyerhof, 1951;Hjiaj et al, 2005); eccentric vertical loads (Prakash and Saran, 1971;Okamura et al, 2002;Nawghare et al, 2010;Krabbenhoft et al, 2012); and eccentric inclined loads (Meyerhof, 1953(Meyerhof, , 1963Hansen 1961;Purkayastha and Char 1977;Saran and Agrawal 1991;Loukidis et al, 2008;Yamamoto and Hira 2009;Patra et al, (2012Patra et al, ( , 2016; Ornek 2014;Krabbenhoft et al, 2013;Ganesh et al, 2016).…”

“…Based on the work of (Purkayastha and Char, 1977), Patra et al (2012) carried out experimental tests for a strip footing subjected to an eccentric and inclined load embedded in sandy soil. Ganesh et al, (2016) performed a regression analysis of the values of the bearing capacity taken from laboratory model tests reported in the literature by different researchers; they proposed an empirical RF for determining the ultimate bearing capacity of shallow strip foundations supported on sand under eccentric and/or inclined loads.…”

In this paper, numerical computations using the FLAC code are carried out to investigate of the behavior the bearing capacity of strip footings embedded in sandy soil and under large eccentric vertical load conditions. The study focuses on an evaluation of the non-dimensional reduction factor (RF), which is the ratio between the average bearing capacity of an eccentric footing and its bearing capacity when subjected to a central load. The results indicate a significant decrease in RF when the eccentricity increases and the curve of the decrease is parabolic, even in large eccentricity cases. Based on the numerical results obtained, a new formula of the RF is proposed, and the reasons for the discrepancy between the RF proposed by several authors are identified. The values provided by the proposed formula are in close agreement with some experimental results available in the literature.

The ultimate bearing capacity of strip footings is achieved by establishing the statically and kinematically admissible slip line field. The method of rigorous characteristics is applied to address the coupling of stress and velocity fields.Meanwhile, the stress discontinuity line is presented to account for the shear strength of embedded soils. The failure mechanism can be determined by solving the boundary value problems, and such the approach avoids the predefined slip surface. The proposed solutions show good agreement with the existing results, and they are mostly located between the upper and lower bound solutions of numerical limit analysis. The results demonstrate that the obliquely or eccentrically loaded boundary conditions sharply decrease the ultimate bearing capacity. Besides, the negligence of shear strength of embedded soils underestimates the ultimate bearing capacity of strip footings, and the associated flow rule yields the larger bearing capacity because of the overestimated soil strength.
