Résumé / Abstract
One goal of life-cycle cost analysis is to enable comparative cost assessments over a specified period of time, taking into account all relevant economic factors from initial costs to future operation and maintenance costs until the destruction of the structure. The approach proposed in this paper aims at assessing life-cycle economic impacts of the design choice made at the conception stage. The suggested approach takes into account economic considerations during the total life-cycle of structures, which includes construction, management (inspection, maintenance/rehabilitation), end-of-life and also user costs. The proposed framework finally enables to optimize the choice of the design solution by considering economic constraints. Some bridge case studies are considered in this paper to illustrate the comparison between different design solutions.
