A lot of infrastructure is ageing and reaching the anticipated service life. Measurements or inspections performed on ageing bridges can provide information on the actual degradation state and hence the remaining capacity of these structures. Nevertheless, these measurements or inspections also come at a cost, whereas the budgets for maintenance and repair are often limited. Based on pre-posterior analyses, the Value of Information (VoI) of these measurements or inspections can be determined on beforehand and the most optimal measuring/inspection strategy can be chosen. However, applying these VoI analyses to real-world structures, considering the time-dependent and spatial character of degradation, can be challenging. In this work, a case study is considered where the VoI analysis is applied to a reinforced concrete girder bridge subjected to corrosion. Different monitoring strategies are considered, and different times of performing the measurements or inspections are evaluated. The influence of some parameters, such as the failure cost and the threshold for performing an action based on the measurement or inspection outcomes, has been investigated. The VoI is evaluated for two cases: one with low exposure (corrosion due to carbonation) and one with high exposure (corrosion due to chlorides). In the first case, the degradation rate is very low, and no repairs are required within the considered time span. Monitoring does not induce an intervention and hence will lead to a negative VoI. In the case of chloride-induced corrosion, a positive VoI is found for some time steps and the VoI reaches a maximum in the considered time span. This could be ascribed to the fact that monitoring triggers an intervention for this situation. In this case, changing the threshold that triggers the intervention will affect the VoI and, consequently, the most optimal measuring/inspection strategy.
