Comparison of Experimentally Measured Deformation of the Plate on the Subsoil and the Results of 3D Numerical Model

Abstract

The purpose of this paper is to compare the measured subsidence of the foundation in experiments and subsidence obtained from FEM calculations. When using 3D elements for creation of a 3D model, it is, in particular, essential to choose correctly the size of the modelled area which represents the subsoil, the boundary conditions and the size of the finite element network. The parametric study evaluates impacts of those parameters on final deformation. The parametric study is conducted of 168 variant models.

Experimental and Numerical Analysis of Interaction Between Subsoil and Post-Ensioned Slab-on-Ground

“…Based on a parametric study [6,7] and the effect of the parameters of the 3D model on deformations, the dimensions of the modelled area of subsoil were chosen to be 6.0 x 6.0 x 6.0m with the boundary conditions set as mentioned above. Figure 4 shows the total vertical displacement of the subsoil model.…”

Experimental measurements of subsoil–structure interaction and 3D numerical models

“…Soil is heterogeneous material and its properties are different from idealization linear elastic isotropic homogeneous substance. Therefore, the calculated values of the settlement do not correspond with the real values measured in real buildings or during the experiments (Labudkova and Cajka, 2014;Cajka and Labudkova, 2015). Inhomogeneous half-space was used for the analysis of the interaction of subsoil and loaded steel-fibre reinforced concrete slab, reinforced concrete slab and also post-tensioned concrete slab.…”
