Abstract
In this paper, a new prediction methodology to deal with longitudinally invariant soil-structure interaction problems in elastodynamics is presented. The method uses the finite-element method to model the structure, the boundary-element method to model the local soil surrounding the structure and the method of fundamental solutions to model the wave propagation through the soil. All those methods are formulated in the two-and-a-half-dimensional domain. The methodology is firstly verified in the ...
