Abstract

Purpose and Methods

This study investigates the characteristics of bridge–abutment interaction based on the vibration spectra of the recorded vibration responses of the abutment, which characterize the vibration transformation from the bridge to the abutment. To this aim, the abutment response excited by a moving truck on the bridge is used to evaluate the transmissibility of the bridge–abutment path. The test results are compared with the vibration spectrum of the bridge vibration responses.

Result and Conclusion

It is found that the vibration transformations from the bridge to the abutment and the abutment to the bridge have an identical specific frequency. The interactions between the bridge–abutment paths qualified using a passing vehicle can be used for structural health monitoring.
