ASCE NCS-SEI June 2024 Meeting
Corrosion Protection Plan for 100-Year Service Life
Click HERE for the registration link.
Owners are using the design-build vehicle to deliver signature and expensive bridges. In this process, owners specify performance-based design where the service life of various replaceable and non-replaceable members is defined in the RFP. The means and methods of achieving the specified service life is left to the design-build team. AASHTO manuals refer to the use of design for service life to ensure that structures are designed to achieve 100 years of service.
The Fib 34 model predicts the service life of RC elements (with a 90% confidence level) exposed to chlorides based on the chloride loading, concrete permeability data (chloride migration coefficient), rebar material, design cover, and several other factors. Based on the modeling results, engineers select a specific combination of rebar cover, concrete mix design, and rebar material to achieve a 100-year life. The life cycle cost of each option is compared to select the best option for each environment (deck, superstructure, substructure, etc.).
This presentation will review the several factors that must be effectively addressed during the design stage to achieve a 100-year service life. Material/corrosion experts retained along with the design team can significantly help avoid factors that cause premature deterioration in structures.
