Special Issue Information

Dear Colleagues,

Structural health monitoring (SHM) is to detect structural damage or degradation by analysing and evaluating the performance of a structural system through structural response using non-destructive sensing technology in the field. The process of structural health monitoring is to obtain the dynamic response measurement of the system timing sampling through a series of non-destructive testing sensors. Then, the characteristic factors sensitive to damage are extracted from these measured values, and these characteristic factors are statistically analysed to obtain the current health status of the structure. In the future, structure health monitoring technology should be transformed into automatic systems with minimal manual intervention, no damage to the structure, online real-time continuous monitoring, inspection and damage detection. In addition, the technology should enable the system to automatically report the status of the structure through the local area network or remote centre. Therefore, the identification accuracy of structural health monitoring systems is strongly dependent on non-destructive testing sensors and data processing and analysis algorithms.

The purpose of this Special Issue is to introduce the new generation of non-destructive testing sensors and mass data intelligent processing and analysis algorithms for structural health monitoring, with its scope including but not limited to the following topics:

  • The research and development of non-destructive testing sensors and supporting equipment;
  • Abnormal data diagnosis methods based on deep learning algorithms;
  • Structural damage identification methods based on computer vision technology;
  • Structural health monitoring methods and related devices based on digital twin;
  • Multi-source heterogeneous monitoring data fusion;
  • Health monitoring methods for large complex structural systems.

During a heavy traffic flow featuring a substantial number of vehicles, the data reflecting the strain response of asphalt pavement under the vehicle load exhibit notable fluctuations with abnormal values, which can be attributed to the complex operating environment. Thus, there is a need to create a real-time anomalous-data diagnosis system which could effectively extract dynamic strain features, such as peak values and peak separation from the large amount of data. This paper presents a dynamic response signal data analysis method that utilizes the DBSCAN clustering algorithm and the findpeaks function. This method is designed to analyze data collected by sensors installed within the pavement. The first step involves denoising the data using low-pass filters and other techniques. Subsequently, the DBSCAN algorithm, which has been improved using the K-Dist method, is used to diagnose abnormal data after denoising. The refined findpeaks function is further implemented to carry out the adaptive feature extraction of the denoised data which is free from anomalies. The enhanced DBSCAN algorithm is tested via simulation and illustrates its effectiveness while detecting abnormal data in the road dynamic response signal. The findpeaks function enables the relatively accurate identification of peak values, thus leading to the identification of strain signal peaks of complex multi-axle lorries. This study is valuable for efficient data processing and effective information utilization in pavement monitoring. Full article

In structural health monitoring (SHM), most current methods and techniques are based on the assumption of linear models and linear damage. However, the damage in real engineering structures is more characterized by nonlinear behavior, including the appearance of cracks and the loosening of bolts. To solve the structural nonlinear damage diagnosis problem more effectively, this study combines the autoregressive (AR) model and amplitude-aware permutation entropy (AAPE) to propose a data-driven damage detection method. First, an AR model is built for the acceleration data from each structure sensor in the baseline state, including determining the model order using a modified iterative method based on the Bayesian information criterion (BIC) and calculating the model coefficients. Subsequently, in the testing phase, the residuals of the AR model are extracted as damage-sensitive features (DSFs), and the AAPE is calculated as a damage classifier to diagnose the nonlinear damage. Numerical simulation of a six-story building model and experimental data from a three-story frame structure at the Los Alamos Laboratory are utilized to illustrate the effectiveness of the proposed methodology. In addition, to demonstrate the advantages of the present method, we analyzed AAPE in comparison with other advanced univariate damage classifiers. The numerical and experimental results demonstrate the proposed method’s advantages in detecting and localizing minor damage. Moreover, this method is applicable to distributed sensor monitoring systems. Full article

In this paper, a different approach to the traditional literature review—literature systematic mapping—is adopted to summarize the progress in the recent research on railway catenary system condition monitoring in terms of aspects such as sensor categories, monitoring targets, and so forth. Importantly, the deep interconnections among these aspects are also investigated through systematic mapping. In addition, the authorship and publication trends are also examined. Compared to a traditional literature review, the literature mapping approach focuses less on the technical details of the research but reflects the research trends, and focuses in a specific field by visualizing them with the help of different plots and figures, which makes it more visually direct and comprehensible than the traditional literature review approach.
