Feasibility of Bridge Structural Health Monitoring Using Short Term Data Acquisition System

Long-term testing of bridges can be expensive and result in a large amount of data that is difficult to manage and analyze. The purpose of this study was to investigate the feasibility of a short-term data acquisition system that used a minimal number of gauges to quantify a bridge's behavior. As a result, a system was developed that could use up to eight sensors and could be utilized in the field for up to two weeks on two marine batteries. Once the system was developed, it was installed on a bridge near Perry, Utah. This particular bridge had a permanent data acquisition system installed so a direct comparison could be performed as well as with data that were recorded during a live-load test. In general, the short-term data acquisition system performed well. It was determined that two marine batteries did not supply enough power to operate the system for the desired two week period. Future work will investigate a sleep mode that should conserve additional energy and prolong the operating life of the system. The measured results were similar to those recorded with the permanently installed system as well as the live-load data. While the testing of the system was successful, additional work needs to be performed prior to implementation. Specifically, the battery issue needs to be resolved to prolong the viable operation time of the system. Additionally, improvements to the software in terms of post processing and capabilities could be improved to make it more useful to the user.
