Updating bridge management system in Korea considering recent subjects in bridge management

The bridge population in Korea has greatly increased since the 1990's. The major bridge authorities in Korea can be divided into three; the central government, the express way corporation and the local governments. The history of the BMS with the central government goes back to the middle of 1980, however, the application of the BMS has been limited very much because it did not include some important issues in bridge management such as structural safety, realistic life-cycle cost data and solution finding strategies. To overcome these restraints, the Korean government has launched a new project to revise the current BMS, including not only practical approaches of realistic cost data and condition status but also research finding bridge deterioration models in terms of safety and decision making processes which is appropriate for local conditions and the environment of Korea. In this study, the current status of the bridge management system development in Korea is introduced including several key issues such as the analytical/computational framework for statistical regression and reliability based models for bridge member degradation and optimized decision making strategies considering preventive/demanded maintenance.
