Passive tuned mass damper (TMD) is a stand-alone vibrating system attached to a primary structure and designed to reduce vibration of the structure at selected frequency. This study focuses on the application of single or multipleTMDs on Euler-Bernoulli beams and examines their effectiveness based on free
and forced vibration characteristics of the beams, i.e., the primary structures. There is a gap in the existing literature in terms of free and forced vibration analysis of beams carrying any number of concentrated elements. There are methods developed for the free vibration analysis but they are not practical due to the complex mathematical expressions. Numerical assembly method (Wu and Chou, 1999) is used to determine free vibration characteristics of beams in order to get over the drawbacks of other approaches in the literature and forced vibration response is obtained based on modal analysis approach and orthogonality condition.
