• Abstract:
  Long-term testing of bridges can 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 bridges 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 ; was 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.
