Optimal Design and Practical Considerations of Tuned Mass Dampers for Structural Control

Optimal Design and Practical Considerations of Tuned Mass Dampers for Structural Control 

Vibration control of structures using supplemental devices against natural and man-made excitations has been atopic of interest in civil engineering in recent decades. Among those devices, tuned mass

In Den Hartog s study, an undamped SDOF dynamic system subjected to sinusoidal loading was considered. For a given mass ratio ofTMD to the primary stmcture, p, he suggested that the optimal frequency ratio ofthe TMD to the primary, (r and the optimal damping ratio ofTMD, ( J, can be calculated by the following equations 

The vibration control effectiveness of TMD is achieved by changing the dynamic characteristics, specifically the damping properties, of the struc-
