Abstract
A Literature Review of Non-Contact Tools and Methods in Structural Health Monitoring
Highlights
Large-scale structures and infrastructures including buildings, bridges, dams, aircraft, rails are subject to damage and deterioration throughout their lifecycle [1,2]
This document reviewed the most relevant methods and tools that exhibit many different contactless methods taken for structural health monitoring in the last 25 years
There is a clear trend in utilizing vision-based tools like the computer become more powerful and algorithms are capable to accurately post-process the data
Summary
Large-scale structures and infrastructures including buildings, bridges, dams, aircraft, rails are subject to damage and deterioration throughout their lifecycle [1,2]. SHM systems differentiate from traditional damage detection systems because it integrates automated health assessment analytics with data sensing, from which a more efficient structural condition valuation can be formulated [7]. The complexity of the systems can be classified into four levels: detection, localization, the extent of damage, and prognosis of a remaining lifetime. In simple terms, they begin from only detecting the presence of damage, to characterize the severity and predict the remaining lifetime [7,8]
