Major sources (and conduits) of ground-borne vibration include railway lines and tram tracks, traffic from heavy motorised trucks and military equipment, heavy industrial machinery, and buildings which emit heavy vibration such as power plants. As population density increases, buildings are being constructed ever closer to these sources of vibration (particularly railway lines), requiring that they be ‘negatively’ isolated, to reduce the upward passage of vibration to the building structure. High load capacity rubber bearings, generally of low deflection, are the most common form of building isolators, however in ultra-critical applications such as music auditoriums, structural spring isolator systems can be used, offering higher deflection.
