Artificial Intelligence in Civil Infrastructure Health Monitoring

Civil infrastructure, encompassing buildings, bridges, dams, and other critical structures, is the foundation of modern society. The safety, longevity, and efficient operation of these structures are crucial for societal well-being and economic stability. Structural health monitoring (SHM) plays a pivotal role in achieving these objectives by continuously tracking and assessing the condition of infrastructure. SHM enhances the resilience of structures by providing real-time data on their health and supporting proactive decision-making during extreme events such as earthquakes, floods, or hurricanes. 


Regular monitoring is essential for identifying potential issues or defects in infrastructure. Detecting structural weaknesses early can prevent catastrophic failures that could endanger lives and property. Timely repairs and maintenance based on monitoring data help maintain the structural integrity of these critical assets. Monitoring provides valuable insights into the aging process of structures. Understanding how materials degrade over time allows engineers to implement measures that extend the lifespan of infrastructure. Proper maintenance, informed by monitoring data, ensures structures remain functional and reliable for extended periods. 


Advancements in monitoring technology have enabled real-time data collection and analysis. Predictive maintenance based on this data reduces the need for reactive repairs, saving costs and minimizing disruptions. This proactive approach enhances the efficiency of maintenance practices and resource allocation.
