DESCRIPTION:A tuned mass damper (TMD) is a simple\, reliable and effective
  vibration control device employed in many civil engineering structures ar
 ound the world\, ranging from pedestrian bridges to the tallest skyscraper
 s. TMDs may be used for a whole range of dynamic loading scenarios\, thoug
 h they are primarily used to resist wind and seismic loads which structure
 s may be subjected to. Traditionally\, TMDs have been designed (its parame
 ters have been optimised) based on structural\n(fixed-base) properties alo
 ne. However\, soil foundations may have a significant influence on the dyn
 amic response behaviour of structures. \nAdditionally\, the overwhelming m
 ajority of studies into TMDs have been analytical in nature. As part of th
 is research\, a series of geotechnical centrifuge tests were conducted to 
 investigate the seismic response behaviour of sway frame structures for a 
 range of soil foundations and different TMD configurations. The experiment
 al test-set ups and results will be presented during this talk.\n
