Comparison of Measured Displacement of the Plate in Interaction with the Subsoil and the Results of 3D Numerical Model

Abstract

In the context with the solution of interaction of foundation structures and subsoil is complexity of a static solution given mainly by selection of a computational model, effects of physical-nonlinear behaviour of such structure and co-effects of the upper structure and the foundation structure. The purpose of this paper is to compare subsidence of the foundation measured during the experiment and numerical calculations based on FEM. This paper describes how calculated deformations depend on parameters of subsoil modelled by 3D finite elements. The parametric study includes charts of the dependence of resulting deformation on the choice of boundary conditions, on the size of the modeled area represents the subsoil, on the depth of 3D subsoil model and the size of the ground area 3D subsoil model.

Experimental Static Load Test of Concrete Industrial Floor Model

“…This experiment bring many information about influence of punching share phenomenon on slab-on-ground. Measured data will serve for creating of numerical model by FEM (finite element method) [10]- [12].…”

Design of Bitumen Asphalt Belt Sliding Joint Based on Experiment Results

“…Numerical analysis in civil engineering is mostly provided with software based on finite element method. There are a few possibilities of modelling the complex problem of sliding joint: special interface between areas (surfaces), contact elements or parametrical model of subsoil, numerical modelling of sliding joint and soil structure interaction generally is mentioned also in [3,9,17]. It is necessary to take into consideration experiment result for particular materials adequately to the relevant numerical model.…”

Numerical Modeling of the Subsoil-Structure Interaction

“…If a 3D model of a linear homogeneous isotropic half-space is created using 3D finite elements the size of the modeled area representing the subsoil, choosing of boundary conditions and determination of the size of finite-element mesh greatly affects the resulting deformation. These dependencies were pursued in the detailed parametric study [5,6]. Parametric study proved that the calculated deformation increases with increasing dimensions of the modelled area.…”
