Abstract:

Strengthening structures with Fiber-Reinforced Polymer (FRP) composite systems has been growing in popularity over recent years for the many benefits that the technology offers. The umbrella project, “Preservation of Missouri Infrastructure: Validation of FRP Composite Technology Through Field Testing”, also known as the Five Bridges Project, was designed to push forward composite strengthening schemes for use on real structures. Using real structures demanded that the strengthened structures be monitored for performance to prove that the composites were working and that they were not losing strength over time. Monitoring the structures meant scheduling load tests for all five bridges. Difficulties in using traditional monitoring equipment, like Linear Variable Displacement Transducer (LVDT) systems, on these structures ordered the search for a better monitoring system. This report presents high-precision Surveying Equipment as a new serviceability monitoring system for load testing; the materials, procedures, and data analysis techniques are discussed as well as a comparison between serviceability monitoring systems. This report also presents the results of the load testing. All five bridges are compared in terms of serviceability before and after strengthening results to show the overall performance of these strengthening schemes. Normalization of the deflection data due to varying truck weights and thermal effects was conducted to help compare the individual tests to one another. Bridge deficiencies and deterioration are also discussed and noted to help establish a reference for future testing and inspections.
