Reliability analysis of existing sheet pile walls based on the 1-year reference period
report
Deterioration caused by corrosion is a concern for asset management of steel sheet pile walls at the end of their design lifetime. Aiming to support decision-making related to lifetime extension, TNO has performed research within the Kennisprogramma Natte Kunstwerken on the reliability assessment of deteriorating sheet pile walls and on the reliability updating based on inspections and load testing. The structural reliability of existing sheet pile walls has been investigated in terms of the annual probability of failure. The 1-year reference period enables the updating of the structural reliability in a rigorous way by accounting for available structure specific information and the point in time when the information is gathered. The annual probability of failure has been estimated by using the First Order System Reliability method and the Equivalent Plane method in combination with a simplified model of the behaviour of the soil-structure system. The focus of the reliability investigation is on the ultimate limit state of yielding of the steel profile
