In this paper, a research was performed to estimate dynamic characteristics of bridges using wireless sensors. First, the developed wireless sensors were compared with wired sensors through laboratory tests. Field tests were carried out on a steel box girder bridge. Dynamic characteristics of the test bridge were identified from the measured data by wireless sensors. As a result, it was proven that the wireless sensor system could be effectively applied to the measurement of large civil-infra structures.
