Numerical solution of soil - foundation interaction and comparison of results with experimetal measurements

Abstract

Several experimental measurements of reinforced concrete slab - subsoil interaction are compared with numerical analysis of shallow foundation by means of FEM. At the Faculty of Civil Engineering VSB - Technical University of Ostrava testing device was constructed so that the phenomena of soil - foundation interaction could be experimentally investigated and compared with numerical models. Results of experimental loading test are compared with soil - foundation interaction analysis based on finite element method (FEM). The purpose of this paper is to compare resulting deformation of the slab, subsidence of the subsoil, bending moments and contact stress calculated by different software based on FEM. Currently there are several software that, can deal with the interaction of foundations and subsoil.
