Tuned Mass Dampers (TMDs) are devices that oppose the motion of a floor which has been excited by occupant footfalls. They have been demonstrated to be effective when considered during the design process or in mitigation situations. If designed and implemented properly, they achieve three goals: (1) maintain structural motion levels below commonly accepted criteria, (2) optimize the size and configuration of the structural system in order to provide more useable space in a building, and (3) reduce the cost of construction due to fewer and/or smaller structural elements. Traditionally, TMDs have only been used to control perceptible and excessive motions from wind loading and crowd movement. As such, they have not been used in laboratory and other sensitive spaces due to equipment criteria which specify vibration levels far below perceptibility. With the advent of a new dashpot damper design, it is now possible to use TMDs to control imperceptible motions as required in sensitive occupancies. This paper presents the results of controlled testing of these new dashpot dampers and a full-scale implementation of TMDs with this component in a long-span structure. |
