• Abstract:
  The goal of this work was to move structural health monitoring (SHM) one step closer to being ready for mainstream use by ; the Iowa Department of Transportation (DOT) Office of Bridges and Structures. To meet this goal, the objective of this project ; was to implement a pilot multi-sensor continuous monitoring system on the Iowa Falls Arch Bridge such that autonomous data ; analysis, storage, and retrieval can be demonstrated. ; The challenge with this work was to develop the open channels for communication, coordination, and cooperation of various ; Iowa DOT offices that could make use of the data. In a way, the end product was to be something akin to a control system that ; would allow for real-time evaluation of the operational condition of a monitored bridge. ; Development and finalization of general hardware and software components for a bridge SHM system were investigated and ; completed. This development and finalization was framed around the demonstration installation on the Iowa Falls Arch Bridge. ; The hardware system focused on using off-the-shelf sensors that could be read in either “fast” or “slow” modes depending on ; the desired monitoring metric. As hoped, the installed system operated with very few problems. ; In terms of communications—in part due to the anticipated installation on the I-74 bridge over the Mississippi River—a ; hardline digital subscriber line (DSL) internet connection and grid power were used. During operation, this system would ; transmit data to a central server location where the data would be processed and then archived for future retrieval and use. ; The pilot monitoring system was developed for general performance evaluation purposes (construction, structural, ; environmental, etc.) such that it could be easily adapted to the Iowa DOT’s bridges and other monitoring needs. The system ; was developed allowing easy access to near real-time data in a format usable to Iowa DOT engineers
