Abstract

As a cornerstone of transportation asset management, risk-based approaches have been used to support maintenance decisions of civil structures. However, ambiguous and subjective risk criteria and inconsistency on the use of risk-based approaches can lead to a fuzzy understanding of the risks assessed. Whilst RAMS criteria (reliability, availability, maintainability and safety) are consolidated aspects on multiple industries, such as nuclear or railways, its application in civil structures is still limited. This paper presents a risk-based model to assess the impact of maintenance actions on civil structure and its elements through the use of RAMS criteria. The model proposes a systematic route to prioritising decisions about maintenance interventions and renewals and supports a clear understanding of the risks involved as the reasons for making those decisions, as well as the residual risks where a decision not to intervene is made. Ultimately, the model acts as a catalyst to rethink maintenance risks and creates a platform to enhance communication between maintenance decision-makers.
