Summary
The results of subsoil-structure interaction analyses can be different and depend on the choice of the interaction model. These models are being continuously improved. The analysis of the interaction between the steel-fibre reinforced concrete slab and subsoil was carried out by means of three-dimensional finite element analysis. This interaction was also observed during the loading test in the experimental measurements. Soil is generally heterogeneous, hence its properties are different from the idealized behaviour of the linear elastic isotropic homogeneous material. The modulus of deformability of the modelled area of subsoil varies continuously with increasing depth. The inhomogeneous half-space was used for the modelling. In the parametric study, presented here, the deformations obtained from the analysis of the homogeneous and inhomogeneous half-spaces were compared. The values calculated from the three dimensional finite element interaction models of the subsoil were compared with the values measured during the loading test.
