Research Development Related to Structural Health Monitoring and Integrity for Runyang Yangtse River Bridge
The significance of implementing long-term structural health monitoring and condition assessment systems for long-span bridges, in order to secure structural and operational safety and issue early warnings on damage or deterioration prior to costly repair or even catastrophic collapse, has been recognized by bridge administrative authorities. Developing a long- term monitoring system for a long-span bridge-one that is really able to provide information for evaluating structural integrity, durability and reliability throughout the bridge life cycle and ensuring optimal maintenance planning and safe bridge operation-poses technological challenges at different levels. This paper explores recent technology developments in the field of structural health monitoring and condition assessment for the Runyang Yangtse River Bridge. Some key issues including the baseline finite element modeling, structural damage alarming, serviceability reliability assessment and health: monitoring under Typhoon Victor are discussed in detail. The need for establishing a successful structural .condition assessment system that will bring powerful help to advance the scientific management of the bridge is highlighted.
