In this work a substructure technique is introduced to consider the simultaneous influence of spatially non-uniform soil-structure interaction and ground excitation on the response of bridge structures under strong earthquakes. The bridge structures with their footings and the subsoil are modeled using finite elements and boundary elements, respectively.
