| Modern footbridges tend to be light and might not fulfill the requirements of the Vibration Serviceability Limit State. Passive damper devices such as tuned mass dampers (TMD) are a solution to reduce vibration without adding significant mass to the structure. Usually these damping solutions are considered as a solution strategy for a vibration problem, but not as part of the design. The aim of this study is to investigate the consideration of these devices in the design phase and assess the improvement to the dynamic response of the structure. It was shown how a finite element program can be used to model a footbridge equipped with a TMD and to execute a dynamic analysis. For that purpose an exemplary structure was modeled in SOFiSTiK software and several methods of dynamic analysis have been tested. The benefits of the incorporation of the TMD in the design process is quantified in term of material saving. Furthermore, a physical design of the TMD was carried out including an economic evaluation. | |
