• Abstract:
  Movable bridges have particular maintenance issues, which cost considerably more than those of fixed bridges,
  
  mostly because of the complex interaction of the mechanical, electrical and structural components. In order to track
  
  maintenance and operational performance, 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. In this project, a number of statistical analysis and machine learning-based methods were developed
  
  and employed to track the operation of the mechanical components. After the completion of the previous phases
  
  of the project, the bridge was 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. The research team focused on repairing the monitoring system, which was affected by the painting
  
  operation, collecting and analyzing more data and preparing the system for FDOT. In this phase, the monitoring
  
  system was maintained. 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
  
  mechanical 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 noted in the maintenance logs. Finally,
  
  recommendations are provided based on the findings and experiences from this project.
