Resumen:

Tuned Mass Dampers (TMDs) have shown to be powerful tools to mitigate vibration on structures subjected to external loads (i.e., moving, wind or earthquake loads) due to their robustness, reliability and low cost of maintenance. TMDs have been installed on the superstructure and substructure of bridges, tall buildings, chimneys, monuments, among other special structures. Design of a TMD involves the dynamic analysis of the structure where the TMD is to be attached, and the optimization of the parameters that characterize it. Selection of the mechanical configuration of the TMD depends on the space available to install it and the type of response to be reduced; for these reasons, the implementation of a TMD-system in reducing structural vibration is not straightforward, and needs to be carefully evaluated for the problem at hand. The main objective of this study is to investigate the effectiveness of TMDs installed underneath the superstructure of a curved steel bridge to control its vibration. For the analyses, a three dimensional finite element model with and without TMDs is built and tested under the action of dynamic loading. The results of the analysis are used to compare the structural behavior of the bridge with and without TMDs and to evaluate the effectiveness of the TMD-system considered. Further, the impact of using TMDs that fail to reduce effectively the structural response of the bridge to the maximum is discussed.
