Bridge Frequencies Identification from the Dynamic Response of a Passing Vehicle

Abstract

Based on the coupling nature of a vehicle moving on a bridge, Yang et al [1] proposed an indirect bridge frequency approach where the bridge response can be recorded by the passing vehicle. Then, the bridge frequencies can be obtained from the dynamic response of the moving test vehicle. Following this concept, in this study, an experimental setup was designed for a test vehicle moving on a bridge to measure the bridge frequency. From the present experimental results, the indirect bridge inspection method is feasible for monitoring the dynamic characteristics of a bridge.
