Validation and Analysis of Results from a Bridge Motion Monitoring Experiment

Mark Leach, Michael Hyzak, and Sigrid Horoschak

Abstract:	Additional analysis of data from an experiment in which Global Positioning System (GPS) technology was used to measure the motion of a cable-stayed suspension bridge over the Mississippi River near New Orleans, Louisiana has been performed. An earlier paper, “Results from a Bridge Motion Monitoring Experiment”(l), described the experiment configuration, analysis techniques, and initial results of monitoring bridge motion and displacement. Further analysis has been performed on the original bridge data, including analysis of the frequency and magnitude of motion, as well as correlation of motion among antenna sites. The validity of the earlier results is evaluated by observing GPS data from a device which allows controlled motion similar to what was seen in the original bridge data. The methods of validation and analysis are discussed and the results are presented.
