A review on structural health monitoring: past to present

摘要

The field of structural health monitoring (SHM) has gained significant attention from academia and industry, particularlyin the realm of damage detection. This approach allows continuous monitoring of the structural integrity of systems andstructures throughout their operational lifespan, leading to reduced dependence on periodic inspections and lower maintenancecosts. Importantly, this method enables the assessment of structural degradation without causing actual damage to thestructure itself. Over the past four decades, various evaluation methods for SHM have been developed, with concrete buildingsbenefiting greatly from their implementation. Among these methods, vibration-based techniques provide a quick and efficientway to assess the overall health of a structure. Specifically, frequency-based techniques are commonly employed within thevibrations-based SHM (VBSHM) framework, although extracting these parameters through algorithm development can be acomplex and time-consuming task. This research aims to review VBSHM with a focus on modal parameters, exploring bothtraditional and modern methodologies to enhance the accuracy of structural assessment. Additionally, the study highlightsthe current limitations of research in this field and identifies available studies for further exploration.
