DESCRIPTION:Base isolation is a vibration mitigation option for buildings 
 near sources of ground-borne vibration\, typically railways (surface or un
 derground) and roads. One popular building model used for early-stage desi
 gn of isolation is a single-degree-of-freedom mass-spring model\, which fa
 ils to account for many important features of the system\, among them soil
 -structure interaction. As such\, recent research in Cambridge has sought 
 to develop simple models which nevertheless take soil-structure interactio
 n into account. Building on a reference tunnel-building-foundation referen
 ce model by others against which simple models can be compared\, this talk
  examines the significance of the simplifying assumption that floors of th
 e reference structure can be modelled using beams. The implications for si
 mplified “dashpot” models\, which model the building with semi-infinit
 e columns\, are discussed along with future opportunities for their develo
 pment.
