• Abstract:
  The objective of this document is to provide a rationale for conducting risk assessment of Post-Tensioning (PT) tendons to aid designers in the selection of appropriate corrosion protection strategies for PT systems in bridges. The risk assessment is intended to prioritize the need for protective technologies and processes considering the likelihood and consequences of corrosion damage (i.e., the risk) based on the attributes of specific PT system designs.
