Abstract

This paper explores the meaning and importance of tuning amongst other Tuned Mass Damper (TMD) parameters and describes processes to help ensure that an as-built TMD is properly tuned to the as-built high-rise building. A summary of key TMD components and TMD implementations will be presented as an introduction and review. Next, it will be shown that tuning is a means for optimizing TMD performance. A process using modal characterization tests during tower construction to estimate natural frequencies of the completed tower will be described. Finally, the use of a Frequency Response Function (FRF) as a means for verifying the frequency of a TMD will be proposed.
