Abstract:
Water presence in lower cable anchorages has been a long-term challenge on the Uddevalla Bridge in Sweden, as on several other cable-stayed bridges. To find an ultimate solution to the possible corrosion development, a moisture monitoring system has been installed in two selected anchorages. Over 1Β½ year, the system has provided the base of data required for tracking the formation of condensation, the mechanisms of water ingress and the efficiency of the drainage ways. All the above has also been assessed in relation to different interventions carried out on the anchorages. The monitoring system is currently used to evaluate the effectiveness of a prototype dehumidification system, designed to ensure an internal relative humidity below 40%, which will eliminate the risk of corrosion development. A potential way forward is to develop the moisture monitoring system into a digital twin, enabling to extrapolate the moisture assessment to all anchorages of the bridge. Β© 2024 The Author(s).
