Özet
This paper presents experimental and numerical studies of the vertical stress distribution
beneath the centerline of circular footings resting on sand. Vertical stress values due to circular
load in medium-dense sand were measured using soil stress transducers. Reduced-scale laboratory
model tests were carried out in a square-shaped test box, and vertical stresses were measured at
the centerline of the circular footing at different depths of the sand. In order to determine the effect
of footing width on vertical stress distribution, laboratory experiments were performed on circular
footings of different diameters. In addition, a series of finite element analyses was carried out on the
test model to validate the findings of the experimental study. In the numerical analysis, the sand
was modeled as a non-linear elastoplastic material. The analyses were performed using the finite
element method with two-dimensional axisymmetric and three-dimensional conditions. The results
obtained from laboratory model tests and numerical analysis were compared with the vertical
stress values obtained from the theoretical solution in the literature. Vertical stress distribution in
horizontal planes at any depth from the footing base shows the same characteristic form in all methods.
However, some differences were observed between experimental, numerical, and theoretical results
and were discussed.
