Vibration Control of Bridge-TMDI System Based on Power Method
Investigate a novel configuration of Tuned Mass Damper-Infinitesimal(TMDI)for achieving longitudinal vibration control of bridges under seismic loads.Firstly,simplify the mechanical model of the TMDI system installed on the bridge and present its power balance equation.Secondly,employ fre-quency domain analysis to derive the corresponding displacement spectrum of the main structure,fol-lowed by utilizing augmented Lagrange optimization method to design the parameters.Finally,elucidate the technical advantages of TMDI systems in controlling bridge vibrations from a power perspective and discuss how bridge period and damping ratio impact TMDI's vibration damping performance.
