This model adds one further element for the floor plate.
Long-term effects dominate the excitation of the floor plate and
thus the excitation fundamentally differs from excitation of outer
walls. Adding an extra element for the floor plate leads to a finer
resolution of the dynamic behaviour but increases calculation
times. The floor plate is parameterized via the length of the
RC-chain nFloor, the vector of the capacities
CFloor[nFloor], the vector of the resistances
RFloor[nFloor] and the remaining resistance
RFloorRem.
The image below shows the RC-network of this model.
