Structural Health Monitoring (SHM) is a process that uses various technologies to assess the condition of structures like bridges, buildings, and dams. It involves collecting data on factors such as vibrations, temperature, and stress to detect any changes or potential issues over time. This helps ensure the safety and longevity of these structures. The data collected through SHM can be analyzed to identify problems early, allowing for timely maintenance and repairs. By using sensors and advanced software, engineers can make informed decisions about the structural integrity of a building or infrastructure, ultimately protecting public safety and reducing costs.
