Soil-structure interaction (often referred to SSI) is required when structural and ground displacements are depended of each other.  It is usually required when the relation between soil and structure stiffnesses are comparable. On those cases a coupled structure-soil model is required. 

This 1 hour course will cover the theoritical background of soil interaction analysis with application method according to PD 6694-1:2011. Attendees will get many useful knowledge on the integral bridge design.
