A MATLAB toolbox for soil–structure interaction analysis with finite and boundary elements

In this work the numerical model SSIFiBo developed in MATLAB to study dynamic soil-structure interaction problems is presented. The model is based on a three dimensional boundary element-finite element coupled formulation in time domain. This model allows computing structural forced-vibrations, as well as seismic responses. Two numerical examples are solved with the proposed technique: ground-borne isolation with open and filled trench, and the seismic response of a tall chimney.
