Phase II Structural Health Monitoring and Condition Assessment of Chulitna River Bridge

PI: J. Leroy Hulsey (UAF)
Dates: 03/01/2012 – 11/01/2013
Final Project Report: PacTrans-13-UAF-Hulsey

In this study, we will monitor the behavior of the Alaska Chulitna Bridge for the specific purpose of assisting the DOT in performing an accurate condition assessment of this bridge.

Based on the state-of-the-art SHM knowledge and technologies with a specific interest in those which could be used on bridges in cold, remote regions, the objective of this study is to provide important information for structural condition assessment of the Chulitna River Bridge.

Proposed SHM objectives are listed below—applicable to all bridges:

  • Develop a SHM protocol including preferred system integrator, software, instrumentation, and sensors suitable for Alaska’s remote, harsh weather locations.
  • Develop criteria to incorporate SHM into the state’s bridge management process.

The established SHM system for ADOT&PF will be able to monitor performance of bridges subjected to extreme temperature and conditions—an aspect that is very important information for assessment of the structural condition and potential remaining service life of Alaska bridges.
