• Abstract:
  The objective of this study was to investigate the effectiveness of using ultra-high toughness (UHT) steel in bridges to improve the structural reliability for the fracture limit state. The work included literature review, identification of candidate UHT steels, initial material characterization of all candidate steels, in-depth material characterization of the most promising candidate steel, and life-cycle cost analyses to demonstrate the potential benefits of using UHT in realistic bridge structures. This report describes the research program and provides conclusions and suggestions for future work.
