Cálculo de estructuras de barras incluyendo efectos dinámicos de interacción suelo-estructura. Modelo mixto de elementos finitos y elementos de contorno.

[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.
