Experimental and Numerical Studies of Vertical Stresses Beneath the Circular Footings on Sand

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, experiments performed diameters. addition, series finite element analyses was validate findings study. analysis, modeled as non-linear elastoplastic material. The method with two-dimensional axisymmetric three-dimensional conditions. results obtained from analysis compared theoretical solution literature. horizontal planes any depth base shows same characteristic form all methods. However, some differences observed between experimental, numerical, discussed.
