Dear All
I am trying to include tuned mass dampers in footbridges. Someone who recommend me how can I calculate the properties for tuned mass dampers in footbridges to minimize the acceleration keeping the TMD relative displacement.
Thanks a lot
Best regards,
Nati
Hi Nati,
you might be interested in a paper by Krenk and Hogsberg
"Tuned mass absorber on a flexible structure", Journal of Sound and Vibration, Vol. 333 (2014) pp. 1577--1595.
Best regards,

The tuned mass damper has been thoroughly treated in chapter 9 in my book "Structural Dynamics", SpringerVerlag, 2014. Good luck.
there are many resources about the TMD now, actually, you can consider the mass as a variable during the modelling. If the mass can be tuned, so the natural frequency will be changed. then, the resonance of structure will be avoided.
I don't wish for this to look like I am advertising my book, but in Chapter 7 of my textbook Applied Dynamics there is a detailed discussion of vibration absorbers and tuned mass dampers and the difference between the two.
Sarah, I think you may be right, now that I looked again at the question.
Also, if you look at books on vehicle dynamics, such as the one by Reza Jazar, there is a lengthy chapter of suspension optimization, which is very similar to the concept of tuning a vibration absorber.
