• Abstract:
  Bridge infrastructure is a critical element of the transportation system which makes maintaining its safety and
  
  performance vital to a healthy society. However, the civil infrastructure systems in the United States are decaying
  
  at an accelerated rate due to factors such as aging, drastically increased traffic loads, insufficient funds for
  
  maintenance and management, along with many others. The collapse of the I-35W bridge in Minneapolis,
  
  Minnesota in 2007 has manifested the drawbacks of the maintenance and management efforts currently
  
  implemented. In the State of Hawaii, bridges are currently managed by the Bridge Section of the Hawaii
  
  Department of Transportation using Pontis, an AASHTO bridge and highway management software package.
  
  The data required for this approach is obtained through periodic visual inspections, which have been shown to be
  
  unreliable and subjective. This project develops an automatic structural health monitoring system that collects
  
  and analyzes realtime data so that structural behavior is continuously assessed. The system includes sensing
  
  instruments, a data acquisition subsystem, a power supply unit, a data transmission unit and a remote server for
  
  data processing and storage. The system is deployed on a highway bridge in Honolulu, HI. The detailed design
  
  and installation of the system are included in this report. Typical monitoring results are also presented to
  
  demonstrate the effectiveness of the system.
