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 stress, strain, and vibrations to detect any signs of damage or deterioration over time. The goal of SHM is to ensure safety and longevity by identifying potential issues before they become serious problems. This proactive approach helps engineers and maintenance teams make informed decisions about repairs and maintenance, ultimately protecting both the structure and the people who use it.
