Plain Definition: The way a building and the ground it sits on affect each other during shaking.

Technical Description: Mutual response of a structure and underlying soil during dynamic loading, which modifies system stiffness and damping.

Use in Design: Especially relevant for soft soils and tall or heavy structures.
