It is demonstrated that such a dynamic monitoring system can serve as an effective tool for long term bridge health monitoring.
The performance benefit associated with the SMA bridges in a long term has not been well recognized by the decision maker, thus, the wide application of SMA within the civil infrastructures is still limited.
Consequently, the condition of CFRP laminate concrete bond becomes a critical element in sustaining long-term bridge load performance.
The proposed output-only time-domain identification procedure utilizing vision-based displacement measurement represents a low-cost method for either periodic or long-term bridge performance assessment.
The proposed numerical modeling methodologies allow long-term bridge response prediction, recognizing that an IAB has significant time-dependent response changes as a result of irreversible soil structure interaction and time-dependent effects of the superstructure in the case of prestressed concrete girders.
(d) to (j) relating to contents of research program, exploratory advanced research, long-term pavement performance program, seismic research, infrastructure investment needs report, Turner-Fairbank Highway Research Center, and long-term bridge performance program, respectively.
A comprehensive CFRP-strengthened bridge inspection and maintenance program with periodic testing and evaluation of the CFRP plate bond condition is necessary to support and sustain long-term bridge performance.
Owners using CFRP-structural systems on large numbers of bridges within a national transportation system have an ongoing requirement to evaluate the bond condition of FRP composites applied to RC highway bridges in order to monitor long-term bridge load performance.
"Can this plan be a bridge to a long-term solution or will it bridge back to square one?" he said.
The results may provide a baseline data for future field ACM bridge capacity rating assessments and also serve as part of a long-term performance of ACM bridge superstructure.
This support may facilitate therapeutic intervention, bridge to recovery, bridge to a long-term support device, heart or lung transplantation, or bridge to palliation.
