“…It can be observed that for strip (r i /r o = 1) and circular (r i /r o = 0) footings, the N c values from the present study lie between the corresponding values of the lower and upper bound results of Kumar and Chakraborty [6]. For intermediate values of r i /r o , however, the results from the present study, Lee et al [8] and Remadna et al [7] are seen to be greater than the upper bound results of Kumar and Chakraborty [6]. This is attributed to the fact that the analysis of Kumar and Chakraborty [6] is based on the assumption that the value of r h remains always equal to the minor principal stress.…”

This is attributed to the fact that the analysis of Kumar and Chakraborty [6] is based on the assumption that the value of r h remains always equal to the minor principal stress. However, in the present analysis, the value of r h is assumed equal to (i) the minor principal stress corresponding to an outward mechanism, and (ii) the major principal stress for an inward mechanism.…”

“…It can be observed that the values of N c from the present study are found to be close and a little bit smaller than the results of Lee et al [8] and Remadna et al [7].

“…As compared to the factors N c and N q , the effect of the roughness of the footing has a more predominant effect on the bearing capacity factor N c . Table 1 compares the values of N c obtained from the present study with that presented by (i) Kumar and Chakraborty [6] for smooth and rough footings on the basis of the lower and upper bound finite elements limit analysis in conjunction with linear programming, (ii) Lee et al [8] by using PLAXIS for a rough footing, and (iii) Remadna et al [7] on the basis of FLAC for smooth and rough footings. The values within and outside the parentheses correspond to rough and smooth footing, respectively.…”

“…Benmebarek et al [5] also used FLAC to compute N c for smooth and rough ring foundations for both associative and non-associative flue rules. Kumar and Chakraborty [6] employed the lower and upper bound finite elements limit analysis for evaluating the bearing capacity factors N c , N q and N c for ring foundations. Recently, under undrained condition, the bearing capacity factor N c was computed by (i) Remadna et al [7] by using FLAC, and (ii) Lee et al [8,9] by using the finite element code PLAXIS.…”

Unlike the flat base foundations, the determination of the bearing resistance of the cone-shaped footing in finite element analysis (FEA) might not be carried out without considering the interface model. In addition, the simulations of the FEA is hardly achieved with a large system due to the assembly technique. So, the alternative should be considered. Therefore, this paper proposes a new method for computing the 𝑁 𝑐 , 𝑁 𝑞 and 𝑁 𝛾 factors of the bearing capacity of the rough and smooth cone-shaped foundations by combining the skew boundary condition as the interface model incorporated with the viscoplastic strain method-based meshfree obeying the yield equation of the Mohr-Coulomb (MC). Thus, the factors can be determined exclusively and reported to reach a close agreement with the published data; nevertheless, the discrepancies are also provided. The plastic flow of the soil mechanics is discussed thoroughly. In addition, the effects of soil friction angle (𝜙) and cone-shaped angle (𝛽) on the factors are inspected systematically. Accordingly, the conservation of the Terzaghi's superposition assumption is confirmed, and the bearing capacity factor charts can be established for various combinations of 𝜙 = 5 o -45 o and 𝛽 = 30 o -180 o . Therefore, it may conclude that the results produced by these techniques and the techniques themselves may be applied confidently for solving geotechnical problems, especially for computing the bearing resistance of the soil.

Synthesis of PANI/AlOOH composite for Cr(VI) adsorption and reduction from aqueous solutions

et al. 2019

In this study, polyaniline rafted to the surface of AlOOH (PANI/ AlOOH) composites were successfully synthesized and applied for chromium (Cr(VI)) adsorption from aqueous solutions. Cr(VI) adsorption isotherms were described by Langmuir model well and the maximum adsorption capacity was 66.77 mg/g at pH = 5 and T = 298 K. Cr(VI) adsorption was attributed to chemisorption and outer-sphere surface complexation. The interaction mechanism was further investigated by Fourier transform infrared spectroscopy, transmission electron microscopy-energy dispersive spectroscopy and X-ray photoelectron spectroscopy techniques, and the results suggested the partially reduction of Cr(VI) to Cr(III). Cr(VI) removal was mainly related with the electrostatic attraction and chelation of different Cr(VI)/Cr(III) species with protonated nitrogen-containing functional groups (-NH + , -NH-) on PANI/AlOOH.
