5. Analog representation of inertial interaction
5.1 Principle
The developments outlined in the previous chapter implicitly assume that the structure and foundation are integral with the ground. This assumption ignores any soil-structure interaction effect that could lead to a modification of the structure's "dynamic identity" (modification of the natural period and/or damping).
This is known as "inertial interaction".
The diagram in figure 30 presents a simplified analogical illustration of a design...
