A Review of Local Structural Health Monitoring Technology
Abstract
The structure of modern engineering systems is becoming more and more complex, which leads to difficulties in detecting structure damage. Structural damage may cause casualties and economic losses, in order to ensure the safe and reliable operation of these engineering systems, a technology for monitoring and evaluating structure state is needed. Structural health monitoring technology can monitor the dynamic response of the structure in real time with sensors, extract and analyze the sensitive characteristics of damage, and then evaluate the health state of the structure. Structural health monitoring can be broadly divided into two types: global monitoring and local monitoring. This paper briefly introduces several important local structural health monitoring technologies, and focuses on the research progress of local monitoring technology based on Fiber Bragg Grating sensor, electromechanical impedance and smart coating. Finally, this paper discusses the development trend and challenges of local structural monitoring technology.
