Methodology for Risk Assessment of Post-Tensioning Tendons
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. PT system attributes that affect the likelihood of corrosion damage during the service life of a bridge are considered, such as tendon profile, alignment and protection, the surrounding environment, and quality processes used during construction. The consequences of corrosion damage resulting in tendon failure are considered in terms of structural reliability, ease of tendon replacement, and the overall importance of a bridge.
