Abstract

Long-span cable-supported bridges are important infrastructure to our society but subjected to deterioration once they are built due to ageing effects, natural hazards and man-made extreme events. A sudden failure or loss of functionality of the bridges may have severe economic, social and enviornmental impacts. Therefore, it is crucial to implement life-cycle managment (LCM) strategises that could maintain performance of the bridges within acceptable levels in terms of cost-effective intervention actions through their life-cycle (Frangopol and Soliman, 2016). Life-cycle cost and structural performence are two basic but conflicting aspects required for serious consideration in the LCM of the bridges. A life-cycle cost cosists of not only the initial design and construction cost, but also those due to operation, inspection, maintenance and repair during a specified lifetime (Frangopol and Messervey 2007). Structural performnace can be reflected mainly in terms of fucntionality, safety, sustaibaility and reliability. Multi-objective optimization techniques along with the supplementary information, such as the cost of interventions, the status of structures, and the effect of maintenance on the structural performance, should be employed to find the optimum inspection/maintenance types and application times.
