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