Abstract (Summary)

Soil-structure interaction is the interdependence between the foundation structure and subsoil after any static or dynamic solicitation is applied on the surface. Laws of physics that govern the soil mass behavior, soil properties and theory of elasticity simplifications are taken into account to model the foundation structure and subsoil. Foundation structures can satisfactorily be modeled as linearly elastic, homogeneous and isotropic materials. However, soil deposits are more difficult to model due to the way they are deposited in nature (layers of material with different properties). Analytical and numerical techniques have been used to solve these kinds of problems. In this work, a finite element method (FEM) model, using MATLAB, was developed to solve soil-structure interaction problems. Results obtained from this model were compared with results obtained from an analysis made with a coupled finite-boundary element method program (FEM-BEM). Two examples are presented to validate the results obtained from the analysis. The first example was devoted to calibrate the accuracy of the program using the pure FEM results and results obtained from the coupled FEM-BEM. The second example focused on comparing the accuracy of the program using an analytical solution.
