This paper illustrates through Freyssinet experience that stay cable replacement works are highly technical works requiring specialised equipment, techniques and engineering at all stages of the operation. Structural assessment and design, construction methods, work schedule and organisation are closely interconnected and need to be studied in a very coordinated manner by teams having experience in all of these fields. This is necessary to end with a technical solution that is durable according to modern standards, compatible with the structural capacity of the bridge, acceptable for the users in term of disturbance on the bridge operability. Regarding these concerns, parallel strand cables offer significant advantages as they are highly durable, modular, and they require only light equipment and small space for being installed. By extending the service life of bridges without traffic interruption, stay cable replacement operations respond perfectly to the rising demand for sustainable solutions permitting material and cost savings. |
