Loosening of threaded fasteners can cause preload decline, induce bolt fatigue fracture, and
severely compromise the reliability of mechanical products. Loosening detection is an …

Fatigue, corrosion, and bolt loosening are the main causes of structural performance
degradation and collapse in steel bridges. Accurate monitoring of steel bridge diseases is a …

Looseness is the most common form of failure in bolt connections, which can cause safety
accidents by reducing the rigidity of the structural connection, and the detection of bolt …

With the development of signal processing and deep learning, vision-based methods for
loosening detection have progressed in recent years. However, existing visual inspection …

Detection of structural damage is a major concern for engineers. In recent years,
convolutional neural networks (CNNs) have been used for feature extraction and …

The beam-like structures commonly exist in engineering systems and there are many critical
issues relevant to fault diagnosis of those structures. Noticeably, among all other existing …

The problem solved in this research is the diagnosis of the radial clearances in bearing
supports and the loosening of fastening bolts due to their plastic elongation (creep) or weak …

Bolted beam-like engineering structures are frequently encountered with dynamic load-
caused bolt faults like fatigue crack and loosening during operation. Bolt faults can seriously …

Bolts are common and effective fasteners for connecting steel structures, and bolt looseness
detection is essential to ensure structural reliability and equipment safety. However, due to …

Complex grid-like structures such as steel truss bridges and steel truss roofs commonly exist
in civil engineering applications. Since these structures are usually subject to dynamic …
