Résumé / Abstract
The current practice of bridge conception generally focuses on optimizing the economic and performance aspects of the bridge construction. Hence, it does not enable to fully optimize the operation and end-of-life strategies. In particular, maintenance strategies may be different from one design solution to another and one solution can appear to be more attractive at the design stage but less interesting when the entire life-cycle is considered, all the more, when user costs are also considered in the decision process. For these reasons, a holistic approach is proposed in this paper to provide the bridge owner with a complete comparison within a set of design solutions from the construction to the end-of-life. It aims at combining economic, social and performance analyses of bridges during their service lifetime. Several design solutions of a bridge crossing a motorway are considered for illustration.
