Due to the progressive degradation of materials, increase in traffic loads, and natural hazards, bridges may experience some deterioration during their service life and need significant maintenance/rehabilitation actions. There is a huge interest in considering the performance of new superstructures in a life-cycle cost/assessment analysis and optimizing their design and conception by taking into account the overall service life period, from the design/construction to the demolition of the structure. Economical and environmental impacts of construction, maintenance, rehabilitation, demolition need to be considered in the optimization design problem to ensure that new bridges satisfy financial and environmental objectives/constraints.

This special session aims at considering sustainability by means of a holistic approach combining life-cycle assessment, life-cycle cost, and life-cycle performance analyses.
