NONDESTRUCTIVE EVALUATION OF HIGHWAY BRIDGES BY DYNAMIC MONITORING

A Remote Bridge Monitoring System (RBMS) based on measured structural vibration response is perceived to assist in bridge inspection in the future. Measurement of traffic induced vibration is a candidate for the RBMS because of possible automation. However, investigation is needed to develop methods of obtaining consistent data with the RBMS using ambient traffic excitation to eliminate the disadvantages associated with forced excitation. This paper presents such a method to obtain bridge signatures. Tests were conducted on a 1/6 scale bridge model in the laboratory and a full scale bridge in the field. Consistency in obtained structural signatures by the new method and other more conventional methods was examined. Results indicate that the introduced method can be used in the RBMS to obtain bridge signatures.
