Mitigation of Building Motions
Tuned mass dampers (TMDs) are the most commonly used devices for reducing tall structure accelerations and inter‐story drift due to translation and torsion. Generally, TMD effects are not taken into account in strength calculations. Since the 1970s TMDs have been used to mitigate building motions. Examples of buildings in which TMDs were used include the Citicorp Center, New York City, the John Hancock tower, Boston, and the Taipei 101 tower. TMDs consist of one or more masses in the order of 2 percent of the total mass of the structure, added to and interacting dynamically with the structure through springs and damping devices. The structure's motion is reduced by the forces of inertia due to the motion of the TMDs. This chapter describes the TMDs for single‐degree‐of‐freedom systems and two‐degree‐of‐freedom systems.
