Final Technical Report
The Cascadia Subduction Zone along the coast of Oregon and Washington and the Circum-Pacific seismic belt near Alaska present significant seismic and tsunami risks to the Pacific Northwest. These natural hazards are capable of crippling the transportation lifeline infrastructure, particularly bridges, following a major event. Deployment of wireless sensors on transportation lifeline infrastructure would enable rapid evaluation of the condition and effective deployment of first responders and increasing the community resilience and safety of the transportation network.
In ongoing phase one of this work, “Deployment of Low-Cost Wireless Sensors for Real-Time lifeline Condition Assessment”, a sensor was developed to assess the condition of bridges following a natural hazard. Off-the-shelf hardware was adopted to minimize initial investment and increase ease of installation for long-term deployments. However, a test bed deployment on a representative structure is necessary prior to wide-spread use. The goal of this work is to prepare the sensor for real-world deployment, select an appropriate bridge, and evaluate the performance under realistic conditions. Therefore, the deployment and validation of the sensor is critical towards wide deployment throughout the Pacific Northwest transportation network which would allow rapid evaluation of the current state of the transportation network.
