Abstract or Summary
  • The Pacific Northwest is at risk for significant seismic and tsunami events, which are capable of severely damaging lifeline transportation infrastructure, particularly bridges. As the bridges in the United States age and begin to show signs of fatigue, the risk for severe damage increases. Proper monitoring and inspection of bridges is becoming increasingly important as bridges age, especially with the high likelihood of a significant seismic event. Structural health monitoring systems can be used to evaluate the condition of bridges throughout the area, and to quickly determine the state of lifeline bridges after a disaster. With technology advancing rapidly and making widespread monitoring possible, there exists a gap between the monitoring systems and the interpretation and presentation of recorded data. A framework needs to be developed to relay useful information to the owners and decision makers based on sensor readings. This project develops OpenSees bridge models, and uses them to determine a relationship between strain data and damage states that could provide a useful framework for decision making.

  • description.provenance : Rejected by Julie Kurtz(julie.kurtz@oregonstate.edu), reason: Hi Kelli, Everything looks good except the commencement date on the bottom of the title page needs to be changed to - Commencement June 2017 - even if you attended the 2016 graduation ceremony. This date is used for cataloging your thesis with the library and all degrees certified summer 2016 through spring 2017 with have the 2017 commencement date. Once revised, log back into ScholarsArchive and go to the upload page. Replace the attached file with the revised PDF and resubmit. Thanks, Julie on 2016-08-12T16:49:20Z (GMT)
