SS12: Advances in Maintenance and Structural Health Monitoring of Bridges
Summary: Proper and timely maintenance of bridge structures is a crucially important issue confronting civil engineering professionals, in order to extend the life-span of bridges. To reduce the potential risk of structural failure and minimise life-cycle costs, efficient inspection methods and preventive maintenance strategies are needed. Structural health monitoring (SHM) has been adopted by bridge owners and industry as a method with the potential to improve the safety and reliability of structures, thereby reducing operational costs. Although adoption of SHM approaches in industry is on the rise, SHM technology has not yet been widely accepted by working-level officials and bridge owners, despite the significant amount of research activity that is going on. This is probably due to the shortage of satisfactory information for real-world applications. However, recent fast-growing technologies in the fields of sensing, signal processing and pattern recognition have shown immense potential for incorporation in real-world SHM schemes. The aim of this special session is to provide a forum in which scientists and engineers from academia and industry will present state-of-the-art research results on maintenance and SHM technology, focusing on real-world applications and successes. The special session covers, but is not limited to, the following topics: challenges facing real-world applications of SHM; performance evaluation of aged bridges; damage detection; long and short-term applications of SHM; inspection and monitoring-based decision making; structural integrity; novel bridge maintenance methods.
