This paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. To this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. The g...

There can be many reasons for engineers to place the footings near a slope such as leakage of suitable sites or architectural considerations. One of the approaches to increase the amount of bearing capacity, especially in soft soils, is adding stone columns to the soil. In this research, the behavior of a strip footing placed near a stone column reinforced clayey slope was investigated. For thi...

Abstract This paper investigates the use of stability factors for estimating ultimate bearing pressures on cylindrical caissons in cohesive-frictional soils. Rigorous upper and lower bound limit analyses with finite elements axisymmetric (AX) condition are used a series numerical studies. The capacity ( N c 0 , q ? ) surface circular footing firstly revisited. is followed by study effect caisso...

This paper presents a numerical study that utilizes finite element analysis under the plain strain condition performed on sand with isolated strip footing and two closely spaced footings above continuous void. The Bearing Capacity Ratio (BCR) efficiency factor ζγ were introduced to determine effect of void ultimate bearing capacity footing/s. influence various parameters including spacing (S/B)...

www.sciencedirect.com Carbohydrates and their conjugates represent the largest and most varied class of biological macromolecules. While protein and DNA are stuck with their linear arrangement of a limited repertoire of monomers, sugars can be linked to each other (or proteins, lipids) through a range of linkages giving rise to a bewildering and confusing set of tree-like molecules. Consequentl...

This paper presents experimental and numerical studies of the vertical stress distribution beneath centerline circular footings resting on sand. Vertical values due to load in medium-dense sand were measured using soil transducers. Reduced-scale laboratory model tests carried out a square-shaped test box, stresses at footing different depths In order determine effect width distribution, experim...
