The paper deals with the issue of the interaction between the concrete foundation and the subsoil. 2 x 2 m Centrally loaded concrete slab with thickness 150 mm is experimentally tested and analyzed numerically. The aim of the paper is advanced non-linear numerical analysis of concrete slab behavior and use of acoustic emission diagnostics to identify cracks in concrete. The paper presents the results of measurement of acoustic emission and identification of cracks in the bottom surface of the concrete slab. An approximate sectoral localization is also provided for selected acoustic emission characteristics. The results of the measurements are then used for the comparison in numerical calculations. Numerical analysis is based on the use of nonlinear calculation. The calculation is based on fracture-plastic material model for concrete and contacts. The calculation is performed as a variant solution taking into account the various approaches to material properties. The experiment is described in detail. A set of laboratory tests of the material properties is also performed. The laboratory tests include concrete compression strength, split tensile strength and four-point bending test.
