While the early engineering practice has largely considered that the soil-structure interaction has beneficial effects and ignoring it will lead to a larger than expected factor of safety, it is now recognised that such interaction can also be detrimental under certain circumstances. It is therefore important to investigate and understand the SSI effects carefully. From a city scale point of view, where close clusters of buildings are expected the structure-soil-structure (SSSI) interaction is important. In geotechnical earthquake engineering the investigation of SSI and SSSI effects needs high quality data so that reliable analytical or numerical modelling can be attempted. Dynamic centrifuge modelling offers an excellent opportunity to study such effects. In this theme lecture, the recent advances in physical modelling of dynamic soil structure interaction effects will be emphasised. Research carried out on structures fitted with Tuned Mass Dampers (TMDs) and viscous dampers will be presented. Rocking of structures and the ensuing SSI will be considered. Finally, the kinematic and inertial interactions between pile foundation and surrounding soil will be presented.
