Abstract: An attempt is made in this paper to develop a new bridge management system (J-BMS) integrated with the Concrete Bridge Rating Expert System that can be used to evaluate the serviceability of existing concrete bridges. The proposed J-BMS not only evaluates the performance of bridges but also offers the rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. In this system, Genetic Algorithms (GAs) technique was used to search for an approximation of the optimal maintenance plan, and was constructed by using Visual Basic and C language. Furthermore, a comparison of the results of applying this system to some actual in-service bridges with the results of questionnaire surveys to experts shows that optimal maintenance planning as well as bridge rating can be predicted accurately using this system.
