This framework evaluates the impact of multiple damage modes on structural health, suggesting enhanced lifecycle management.
The Value of Information (VoI) framework is a crucial component in evaluating, designing, and optimizing the Structural Health Monitoring (SHM) system by assessing its overall benefit in lifecycle asset management. It focuses on conducting a cost-benefit analysis of decision-making throughout the lifecycle. In practice, the overall damage in a structure consists of multiple damage modes that collectively determine its health. Therefore, it is essential to develop a VoI framework that can incorporate multiple damages and their evolution—first, to evaluate the performance of an SHM system, and second, to optimally design the SHM system. A multi-damage-mode VoI framework is proposed, and its application to the lifecycle assessment of a miter gate structure is discussed.
