Unformatted text preview: oth of the interaction systems.
The concept of the kinematic and the inertial
interaction is very useful, when you will employ FEM
or FDM for the interaction analysis.
When you will performed an analysis using methods
based on the elastic wave propagation theory, a substructural method described after will be more
effective concept. F : Inertia Force of Building and Foundation
