The survey cannot be carried out with traffic present because of the bridge vibration
(97),(98) Video monitoring of the bridge vibration
was extremely helpful for understanding the vibration mechanism.
The maximum acceleration of bridge vibration
reported by Sazonov et al.
The Macdonald, Roberts, and Newland models couple pedestrian motion with bridge vibration
as well as considering the influence of footbridge vibration on the pedestrian lateral load.
Due to the differences in different cross section shape of the girder, the aerodynamic measures for the bridge, on a bridge vibration
suppression effect remarkable suppression measures for another bridge may not be effective need through the wind tunnel test study on the corresponding pneumatic suppression measures.
Therefore, in order to decrease bridge vibration
and to improve the reliability and safety of bridge structures, constructing vibration control systems has become an urgent problem to be solved.
In this system, sensors are used to acquire bridge vibration
. After measurement, sensor modules transfer their data to the data collection device via routers.
2007) with respect to the velocity of the vehicle and the road roughness of the bridge, which are believed to affect bridge vibration
. The velocity of the vehicle was increased by 20 km/h, from 40 to 60 km/h.
However, due to the ratio of the harmonic components amplitude to the base component amplitude and the value of the latter, the shaker is useful to excite bridge vibration
of the frequency above 5Hz.
The bridge vibration
state is relevant to the bridge structure, the vehicle dynamic characteristics, the vehicle speed, and the vehicle flow.
Interestingly, the bridge vibration
shows also a special behavior in the midfrequency range.
