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.
