| Abstract: |
This paper presents the replacement of cable stays of the 33 years old Tjörn Bridge located in Sweden. The bridge has a main span 366 m and a total length of 664 m. The bridge has a locked coil cable system of 64 cables, where some cables have corroded with a number of wire failures. The reason is exposure to water and ice combined with insufficient drainage. The paper describes the full story from detecting the corrosion problem to restoring the safety of the bridge by replacing the cables in a safe way. The paper presents and discusses the history of inspection and identification of the corrosion problem and the challenges and solutions of the replacement of cables. As several cables had been ex-posed to a corrosion risk, the replacements carried out, required an in depth safety analyses to consider the strength of all cables |
