As all bridges get deteriorated over time, structural health monitoring of these structures has become very important for the damage identification and maintenance work.
Evaluating a bridge’s health condition requires the testing of a variety of physical quantities including bridge dynamic responses and the evaluation of the functions of varied bridge subsystems.
In this study, both the acceleration of the deck and the dynamic rotational angle of the bearings in a long-span steel girder bridge were measured when the bridge system was excited by passing-by vehicles.
The nonstationary dynamical phenomena including vibration mode interactions and coupling are observed in response spectrogram.
To elaborate the phenomena, the linear vibration mode properties of the bridge are characterized by finite element analysis and are correlated with the specific modes in test.
A theoretical model is presented showing the mechanism of the mode coupling and instability originated from the friction effects in bearing.
This study offers some insights into the correlation between complex bridge vibrations and the bearing effects, which lays a foundation for the in situ health monitoring of bridge bearing by using dynamical testing.
