The objective of this course is to provide engineers with the fundamental concepts of soil-structure interaction (SSI), with special emphasis on practical earthquake engineering applications. The course introduces seismology and the basic concepts of soil dynamics prior to tackle soil-structure interaction. This will give engineers basic knowledge about dynamic soil properties to understand the behavior of soils during an earthquake and how these properties are introduced in SSI analysis. The application of static and dynamic "seismic" cases is illustrated through numerical examples and examples from the literature.
