I wonder how I can model a TMD (tuned mass damper) on my bridge?
The TMD as you know is composed of a mass, springs and dampers.
Should I model it simply by a spring and a concentrated mass? or there is a special function or some other rules to respect !?
In this situation how can we determinate eigenvalues considering the damping of the structure + that of TMD ?
Can you send me please any example of TMD study?
