The major problems affecting the service life of bridges are related to various factors such as fatigue-sensitive details, increased\r\nservice loads, corrosion deterioration, and the lack of proper maintenance. Among them, corrosion deterioration and fatigue\r\ndamages of structures particularly to steel girder bridges are the most common ones. Bridges of different structural forms, at\r\ndifferent locations or under different climates, may suffer from various degrees of deterioration. Steel girders at different positions\r\nof a bridge may also suffer from different degrees of damage.How to effectively maintain the bridge asset at a minimal cost and how\r\nto predict the time for future works are crucial, particularly when government funding sources become stretched. A comprehensive\r\nbridge management framework assisting stakeholders to appropriately and reasonably prioritize their future maintenance-related\r\nworks in their bridge stocks, such that stakeholders can better allocate the limited resources, is utmost concerned. This paper\r\nproposes an integrated life-cycle management (LCM) strategy on steel girders in bridges in which corrosion deterioration and\r\nfatigue damage prediction models are mapped with girders� performance conditions. A practical example to demonstrate the\r\napplicability of the proposed LCM strategy is also illustrated.
