“…Over the same period, Yazdchi et al (1999) used the coupling approach to study the transient response of an elastic structure embedded in a homogeneous, isotropic and linearly elastic half-plane. On the other hand, Tanrikulu et al (2001) proposed a wholly BEM model having non-local boundary conditions that could be applied to the dynamic analysis of a body with two regions. In two later papers, Xu (2003, 2004) returned to the idea of a coupled approach when considering the seismic response of massive, flexible strip-foundations embedded in layered soils.…”

a b s t r a c tSoil-structure interaction emanating from seismic stationary random excitations is studied using the pseudo-excitation method in combination with the precise integration method. The soil considered is a viscoelastic, transversely isotropic and layered half space and the structure which it supports is modelled by the finite element method. The excitation sources are random field ones that are stationary in the time domain and are located in the soil. The pseudo-excitation method is used to transform this stationary random soilstructure interaction problem into a series of deterministic harmonic response analyses and the precise integration method is used to integrate the ordinary differential equations in the frequency-wavenumber domain. The power spectral densities of the soil-structure interaction responses caused by the stationary random excitations are investigated.

“…In addition, on these boundaries extending to infinity, discretization needs to be truncated, and this leads to errors. In the study of Tanrikulu et al [12], the BEM formulation for infinite non-homogeneous mediums was advanced only for three different layers. However, SBFEM can easily model non-homogeneous soil mediums with many layers extending to infinity.…”

SUMMARYIn this paper, a coupled model based on finite element method (FEM), boundary element method (BEM) and scaled boundary FEM (SBFEM) (also referred to as the consistent infinitesimal finite element cell method) for dynamic response of 2D structures resting on layered soil media is presented. The SBFEM proposed by Wolf and Song (Finite-element Modelling of Unbounded Media. Wiley: England, 1996) and BEM are used for modelling the dynamic response of the unbounded media (far-field). The standard FEM is used for modelling the finite region (near-field) and the structure.In SBFEM, which is a semi-analytical technique, the radiation condition at infinity is satisfied exactly without requiring the fundamental solution. This method, also eliminates the need for the discretization of interfaces between different layers. In both SBFEM and BEM, the spatial dimension is decreased by one. The objective of the development of this coupled model is to combine advantages of above-mentioned three numerical models to solve various soil-structure interaction (SSI) problems efficiently and effectively. These three methods are coupled (FE-BE-SBFEM) via substructuring method, and a computer programme is developed for the harmonic analyses of SSI systems. The coupled model is established in such a way that, depending upon the problem and far-field properties, one can choose BEM and/or SBFEM in modelling related far-field region(s). Thus, BEM and/or SBFEM can be used efficiently in modelling the far-field. The proposed model is applied to investigate dynamic response of rigid and elastic structures resting on layered soil media. To assess the proposed SSI model, several problems existing in the literature are chosen and analysed. The results of the proposed model agree with the results presented in the literature for the chosen problems. The advantages of the model are demonstrated through these comparisons.
