 s Federal Institute of Technology\, Lausanne 1015\nIn major cities around 
 the world\, urbanization and rising land prices have been driving an incre
 ase in real estate development adjacent to\, and above in many cases\, rai
 lway lines and other transportation corridors. Structure-borne sound and v
 ibrations from traffic can be are annoying to human occupants\; if high\, 
 they can also be disruptive to operation of manufacturing facilities\, med
 ical facilities\, and research laboratories. As awareness of structure-bor
 ne sound and vibration issues grow among owners\, designers\, and building
  occupants\, there is a corresponding increase in demand for cost effectiv
 e sound and vibration predictions and mitigation.\nThis research describes
  the development and verification of an analytical model of vibration tran
 smission in an existing four-story building in Boston that is based on the
  floor and column impedances where they are attached. Using geometric prop
 erties\, the authors defined the dynamic behavior of the test structure in
  terms of column impedances (modeled as finite\, wave propagating rods) an
 d floor impedances (modeled as energy dissipating\, infinite plates).\nRes
 earchers performed impact hammer tests as means of verifying the floor imp
 edances. Additionally\, they collected shaker and train-induced vibration 
 measurements near the test column. The authors highlight several aspects o
 f this modeling approach\, and discuss the effectiveness of using this app
 roach to predict the vibration response of buildings subject to ground-bor
 ne vibrations.
