• Abstract:
  Post-tensioned concrete has been used in a number of bridge structures and is expected to be used more in future construction in Virginia. This type of detail offers unique advantages for improving the performance of concrete members. Recent problems in the United Kingdom and Florida have increased concern over the condition of post-tensioned tendons in Virginia's bridges. There is a need for efficient, cost-effective methods of assessing and monitoring the condition of aging tendons in-situ. This study was carried out to survey the literature that addresses the condition of tendons to identify technology, perform a limited assessment of the feasibility of as many of the candidate technologies as possible, and consider follow-on efforts for development and application to post-tensioned tendons in Virginia in was described.
