Machine Learning Algorithms in Civil Structural Health Monitoring: A Systematic Review

Applications of Machine Learning (ML) algorithms in Structural Health Monitoring (SHM) have become of great interest in recent years owing to their superior ability to detect damage and deficiencies in civil engineering structures. With the advent of the Internet of Things, big data and the colossal and complex backlog of aging civil infrastructure assets, such applications will increase very rapidly. ML can efficiently perform several analyses of clustering, regression and classification of damage in diverse structures, including bridges, buildings, dams, tunnels, wind turbines, etc. In this systematic review, the diverse ML algorithms used in this domain have been classified into two major subfields: vibration-based SHM and image-based SHM. The efficacy of deploying ML algorithms in SHM has been discussed and detailed critical analysis of ML applications in SHM has been provided. Accordingly, practical recommendations have been made and current knowledge gaps and future research needs have been outlined.

Automated summary

Machine learning algorithms have gained great interest in the field of Structural Health Monitoring for their ability to efficiently detect damage in civil engineering structures. This systematic review categorizes the diverse ML algorithms into vibration-based SHM and image-based SHM, providing detailed analysis and recommendations for future research.
