SHM role in the Framework of infrastructure resilience

Abstract

Sensor-enabled infrastructure systems are destined to empower resilient communities with more intelligence and sustainability, and therefore enhancing the operational safety of physical infrastructures. Through online and onboard monitoring, the infrastructure components incorporating appropriate analytic and predictive modeling tool not only provides real-Time insight into the operational status of every system and its components, but also enables the trend prediction and timely prognosis of failure before it happens as well as early-stage diagnosis of damage in its incipiency. This paper gives an overview of the importance of structural health monitoring (SHM) for critical infrastructures. It highlights the recent shift from infrastructure monitoring to infrastructure resilience using SHM. The paper also introduces the Infrastructure Resilience Framework (IRF) that encourages the incorporation of innovative techniques, such as optical fiber sensors and machine learning techniques, in infrastructure monitoring. It defines the steps that need to be taken throughout the life cycle of infrastructure.
