The importance of soil structure interaction in seismic design of structures is recognized by the seismic design community, which is very much moving towards performance based design principles. Particularly for structures with deep foundations in soft soil conditions, soil-structure interaction is a key factor that has to be considered in design. Jetty structures can be such structures. However, seismic design standards do hardly provide any straight forward tools for engineers to account for soil-structure interaction in design. It is clear that a challenge exists, which has initiated this study. This paper addresses how Plaxis can efficiently be applied as a tool in seismic soilstructure interaction problems, which has been an important part of the entire MSc thesis study (TU Delft), that has covered a wider range of related aspects.
