Numerical Analysis of Subsoil-Reinforced Concrete Slab Interaction

Abstract

This article presents the numerical modeling of interaction between a reinforced concrete slab and subsoil using ABAQUS. Subsoil was simulated as both homogeneous half-space and inhomogeneous half-space. Reinforcement bars in the concrete slab were accurately modelled allowing capturing a precise deformation profile of the slab in interaction with subsoil. Input data for numerical analysis were adopted from a published work. Results of the study were verified on the basis of comparison with those of the previous study.

Numerical Simulation of the Interaction between Fibre Concrete Slab and Subsoil—The Impact of Selected Determining Factors

“…Approaches to the modelling of the structure-subsoil interaction are characterized by different degrees of simplification of this real, complex, generally non-linear contact problem [25][26][27][28][29][30][31][32][33][34]. The usual approach in the structural engineering is often focused on the most detailed modelling of the foundation structure itself [35] and the subsoil is often simplified by spring models (Winkler, Pasternak, etc.)…”
