The influence of non-uniform soil conditions on the development of ground motions at local sites and the consequence of spatial variation of the amplified ground movements on pounding response are considered. In this study the ground motions of the bedrock are simulated stochastically based on the new Australian design spectrum. The bridge structures, footings and subsoil are described using a combined finite element and boundary element method. The results show the importance of site amplification of the ground motions. The unequal site amplification can strongly contribute to the relative response between the bridge structures and consequently their pounding potential. As expected different soil conditions will provide different pounding response behaviour. In order to estimate pounding damage potential of bridge girders it is strongly recommended that soil-structure interaction and actual site amplification of local ground motions should be taken into account in the analysis.
