SUMMARY:Building on Springs: Towards a Performance-Based Design Approach f
 or Controlling Groundborne Vibration - Dr James Talbot - Structures Group

DESCRIPTION:Base-isolated buildings\, founded on steel springs or elastome
 ric bearings\, have been employed since the 1960s in locations susceptible
  to groundborne vibration.  Examples exist across a wide range of building
 s\, from residential to commercial\, and include specialist buildings such
  as concert halls and hospitals.  In all cases\, the objective is to reduc
 e internal levels of perceptible vibration and re-radiated noise\, with th
 e most common sources of concern being nearby surface or underground railw
 ays.  Despite the extensive use of base isolation\, there is a significant
  lack of guidance on all aspects of design\, from the selection of bearing
  type and their location within a building\, to questions such as how perf
 ormance should be evaluated\, and the most fundamental question of all: is
  isolation necessary?  This talk reviews current practice in base-isolatio
 n design\, and highlights some of the challenges and future research effor
 ts in moving towards a performance-based design approach for controlling g
 roundborne vibration.
