Abstract

The collapse of Ynys-y-Gwas Bridge in the UK is reviewed. The review shows how ingress of chloride into partially grouted ducts and anchorages had caused serious corrosion for tendons. Then a numerical system reliability analysis is carried out to check the limit state function for bending moment. The results shows how the availability of monitoring data from corrosion rate could help the bridge owners to predict the time of the collapse before it happens.
