• 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.
