STRUCTURAL HEALTH MONITORING

In the dissertation, it is established that SHM is a significant development in the field of civil engineering since it changes the periodic and reactive scrutiny of structures to a form of continuous, information-driven to proactive assessments. Contrary to the traditional methods usually used to determine the damage after the deterioration is seen, SHM enables the engineers to monitor the structural behaviour over time and identify the abnormal behaviour at an earlier stage. This renders it useful in bridges, buildings and other structure systems that are subjected to the effects of aging, repetitive loading and environmental influences. The paper also finds that SHM is not just an important monitoring technology but also a decision-support structure. SHM enhances the realization of structural condition and condition-based maintenance by connecting the process of sensing, data interpretation, and maintenance planning. This way, it helps in the infrastructure safety, service life extension and more efficient control of assets. Nevertheless, the dissertation also concludes that SHM also contains limitations. Structural response can be influenced by environmental and operational variability and result in hard interpretation of damage. Moreover, there is a significant gap between research development and the routine fields implementation, which is still a significant problem. Its high price, non-standardization, and difficulty in interpreting the  data, as well as the insufficient institutional preparedness, still limit its broader application, particularly in developing nations.
