Bridge network performance, maintenance and optimisation under uncertainty: accomplishments and challenges
This article presents a critical review of the state-of-the-art in the field of bridge network performance analysis, reliability assessment, maintenance management and optimisation. Previous accomplishments and results are summarised while stressing the aspects of the analysis of a transportation network, which are more challenging for a structural engineer. For instance, the bridge network is described as a spatially distributed system at a scale that is much larger than any individual structure. This requires a different perspective in the modelling of natural extreme events and involves models for the interaction between the individual components (i.e. bridges) and the overall network. Then, the time domain is investigated, and the problem of structural deterioration and its effects on the network performance are addressed. The most important differences between a transportation network and other lifelines are considered next, and techniques for the transportation network analysis and performance assessment are summarised. Finally, a set of selected problems and applications is considered and additional challenges are identified and suggested for future developments.
