000010580 520__ $$2eng$$aThe importance of bridge vibrations induced by moving vehicles, which act as oscillators on a bridge as well as time variant forces, has long been recognized. This vibration can amplify the propagation of existing cracks resulting in further damage to the bridge. It has become one of the causes of reduction in long-term serviceability of the bridge, although major bridge failures are not usually caused directly by moving vehicles. It is also a critical factor to bridge structure fatigue and rapid deterioration since, the vehicle-induced vibration is more critical to bridges with medium to small span; it is worthwhile to investigate the possibility of applying Tuned Mass Damper (TMD) on these bridges. A TMD is a passive type control device with variety of merits in that it has permanent service time and only requires easy management and maintenance efforts and no external power supply source. In order to achieve the above objective, a general formulation of the vehicle-induced bridge vibration controlled with a TMD system is developed here in this paper, which takes into account the road surface conditions. Then, a comprehensive investigation is made to investigate the efficiency of the TMD for suppressing vibrations of bridge under moving vehicles. Such a study is helpful in evaluating the control performance before real control devices are designed in practice. These analytical results will also be useful in carrying out further studies for control strategies suppressing the vehicle-induced bridge vibration
