LCC-based Bridge Maintenance Strategy in Yamaguchi Prefecture

摘要

In this paper, a strategy decision support system for bridge management is described based on bothof the remaining life cycle cost (RLCC) and rebuild cost stabilization, as a joint research projectbetween Yamaguchi University and Yamaguchi Prefecture. The proposed system that considerednot only future maintenance but also rebuild action is applied to existing bridge data on about threeand half thousand bridges that stored in J-BMS data base (J-BMS DB) for practical use. Then, it isfound that the system helps efficiency bridge engineers related to bridge management understandeasily what are the major processes in the deteriorating bridges in the future, how to improve theirperformance, and what kind of repair/strengthening works is most convenient for the deterioratingbridges.
