[EN] This work presents a 2D finite elements - boundary elements coupling model for the harmonic analysis of beam structures founded on viscoelastic domains. The beam structure is modeled by finite elements, whereas the soil is modeled as a homogeneous isotropic viscoelastic boundary element region. The coupling is enforced through a rigid boundary in which equilibrium and compatibility conditions are applied. Formulation and implementation are presented together with some application examples.

[EN]This Ph. D. thesis presents a simple and stable procedure for the estimation of periods and dampings of pile shear buildings taking soil-structure interaction into account. The coupled-system response is obtained by using a substructuring model. A boundary element-finite element coupling formulation is used to compute impedances and kinematic interaction factors of the pile group configurations under investigation. The proposed procedure is applied to perform parametric analyses to determine the influence of the main parameters of soil-structure interaction problems on the dynamic response of the superstructure. The scope of this thesis also encompasses the study of foundations including battered piles.

[EN] 3D BEM-FEM coupling model is used to study the dynamic behavior of piled foundations in elastic layered soils in presenceof a rigid bedrock. Piles are modelled by FEM as beams according to the Bernoulli hpothesis, and every layer of the soil is modelled by BEM as a cointinuum, semi-infinite, isotropic, homogeneous, linear, viscoelastic medium.
