  • Abstract:
    The maintenance costs related to movable bridges are considerably higher than those of fixed bridges, mostly ; because of the complex interaction of the mechanical, electrical and structural components. A malfunction of any ; component can cause an unexpected failure of bridge operation, which creates problems for both land and ; maritime traffic. Maintenance processes associated with the operation system and mechanical parts require ; special expertise. A comprehensive monitoring system was implemented on Sunrise Bridge (Ft. Lauderdale) to ; track the behavior and condition of several critical mechanical, electrical and structural components. A number of ; tests and monitoring of the bridge yielded a wide variety of data, which were analyzed in detail with methods ; developed by the PI and his research team, and the results obtained at the end of the project were reported to ; FDOT in a detailed report. After the completion of this previous project, the bridge was already scheduled for ; painting; however, the monitoring system was significantly damaged during the preparation, sandblasting and ; painting despite the considerable efforts of FDOT personnel to protect the system. This extension project ; therefore focuses on repairing the monitoring system, which was affected by the painting operation, collecting and ; analyzing more data and preparing the system for FDOT. First, details of the field work conducted to repair the ; damaged monitoring system are presented. Then, analysis of data that were collected after the monitoring ; system was repaired is presented for different components. The baseline response and the thresholds for ; acceptable behavior were established. During this phase of the project, unanticipated behaviors were observed ; for two components (one at the span locks and one at the gearbox) at two different times. These findings ; indicating the unanticipated behavior using the monitoring system are also corroborated with the independent ; maintenance reports. These changes in behavior required maintenance work at the span lock and gearbox as ; given in the maintenance logs. Finally, recommendations are provided based on the findings and experiences ; from this project.
