| Abstract: | This paper deals with the suppression of vortex excited vibration of flexible bridges using Tuned Mass Damper (TMD). In the analysis, the semi-analytical nonlinear aerodynamic force model of bridges in the vortex "lock-in" region is employed. Furthermore, the formulas for the best "tuning" of TMD are given based on the TMD parameter optimization. |
