Resumo: A life-cycle cost optimization methodology for a set of bridges, regarding the desired quality level and the available budget, will be presented. The methodology analyses multiple scenarios and evaluates the performance and cost consequences of implementing different types of interventions, in different periods of time. The cost estimation considers the direct and indirect costs of several types of maintenance or rehabilitation works and the deterioration of each bridge is predicted with Markov matrices, based on a condition state index. The methodology was tested on set of 100 concrete road bridges and the results of its application will be presented, as well as some outcomes of its sensitive analysis. The methodology is an approach to support bridge management decisions that could help to optimize the maintenance and rehabilitation interventions plan for a specific group of bridges, during a medium or long period of time, based on life cycle cost minimization.
