Abstract

Structural Health Monitoring (SHM) plays a critical role in ensuring the safety, integrity, longevity and economic efficiency of civil infrastructures. The field has undergone a profound transformation over the last few decades, evolving from traditional methods—often reliant on visual inspections—to data-driven intelligent systems. This review paper analyzes this historical trajectory, beginning with the approaches that relied on modal parameters as primary damage indicators. The advent of advanced sensor technologies and increased computational power brings a significant change, making Machine Learning (ML) a viable and powerful tool for damage assessment. More recently, Deep Learning (DL) has emerged as a paradigm shift, allowing for more automated processing of large data sets (such as the structural vibration signals and other types of sensors) with excellent performance and accuracy, often surpassing previous methods. This paper systematically reviews these technological milestones—from traditional vibration-based methods to the current state-of-the-art in deep learning. Finally, it critically examines emerging trends—such as Digital Twins and Transformer-based architectures—and discusses future research directions that will shape the next generation of SHM systems for civil engineering.
