However, most of works is performed with an assumption that the considered structures are fixed at their base. If soil-foundation-structure interaction (SFSI) is considered at all then linear soil behaviour is often assumed. Works including nonlinear SFSI is very limited. In this study the influence of non-uniform SFSI is considered. It is assumed that the left bridge structure is fixed at its base, while the soil of the right structure can behave nonlinearly. Each bridge structure with footing and subsoil is described by four degrees of freedom. A macro element is used to describe the dynamic behaviour of the footing and soil. The results show that nonlinear SFSI can have a beneficial effect on the activated forces in the structures. However, compared to bridge structure with linear SFSI more pounding occasions are observed and structural settlement can take place.
