Summary

Since most important structures have suffered from micro defects after working for a few years, the health monitoring and condition assessment of these established structures is particularly significant. Smart sensing technology by using different kinds of sensors (i.e., optical fiber sensor, piezoelectric sensor, strain gauge), digital image techniques and remote radar has been performed to monitor the real-time deformation, vibration and damage of the structures. Therefore, a great number of sensing data has been collected, and how to interpret the big data and accurately reflect the physical status of the monitored structures has become an important issue. Static and dynamic structural theories have been adopted to deal with the processing of the sensing data. Artificial intelligence (AI) method combined with the signal processing technique has also been used to recognize the health and damage condition of the structures. Cloud computing technique has also been aided to perform the real-time health monitoring of structures.

 

Thus, the research topic aims to cover original or review articles exploring the innovation in sensing data based structural health monitoring (SHM). The special issue intends to include, but not limited to:

• Smart sensors and structures

• Sensing data based SHM

• Static and dynamic analysis based on sensing data

    Structural Durability & Health Monitoring, DOI:10.32604/sdhm.2024.057759
    (This article belongs to the Special Issue: Sensing Data Based Structural Health Monitoring in Engineering)
    Abstract Addressing the current challenges in transforming pixel displacement into physical displacement in visual monitoring technologies, as well as the inability to achieve precise full-field monitoring, this paper proposes a method for identifying the structural dynamic characteristics of wind turbines based on visual monitoring data fusion. Firstly, the Lucas-Kanade Tomasi (LKT) optical flow method and a multi-region of interest (ROI) monitoring structure are employed to track pixel displacements, which are subsequently subjected to band pass filtering and resampling operations. Secondly, the actual displacement time history is derived through double integration of the acquired acceleration data and… More >

    Abstract Computed tomography (CT) can inspect the internal structure of concrete with high resolution, but improving the accuracy of measurements remains a key challenge due to the reliance on complex image processing and significant manual intervention. This study aims to optimize CT scanning parameters to enhance the accuracy of measuring crack widths and rebar volumes in reinforced concrete. Nine sets of specimens, each with varying rebar diameters and concrete cover thicknesses, were scanned before and after corrosion using an Optima CT scanner, followed by three-dimensional reconstructions using Avizo software.

    Abstract To mitigate the challenges in managing the damage level of reinforced concrete (RC) pier columns subjected to cyclic reverse loading, this study conducted a series of cyclic reverse tests on RC pier columns. By analyzing the outcomes of destructive testing on various specimens and fine-tuning the results with the aid of the IMK (Ibarra Medina Krawinkler) recovery model, the energy dissipation capacity coefficient of the pier columns were able to be determined. Furthermore, utilizing the calibrated damage model parameters, the damage index for each specimen were calculated. Based on the obtained damage levels, three distinct More >

    Abstract Delamination is a prevalent type of damage in composite laminate structures. Its accumulation degrades structural performance and threatens the safety and integrity of aircraft. This study presents a method for the quantitative identification of delamination identification in composite materials, leveraging distributed optical fiber sensors and a model updating approach. Initially, a numerical analysis is performed to establish a parameterized finite element model of the composite plate. Then, this model subsequently generates a database of strain responses corresponding to damage of varying sizes and locations.

    Structural Durability & Health Monitoring, Vol.18, No.4, pp. 445-463, 2024, DOI:10.32604/sdhm.2024.049298
    (This article belongs to the Special Issue: Sensing Data Based Structural Health Monitoring in Engineering)
    Abstract The vibration signals of rolling bearings exhibit nonlinear and non-stationary characteristics under the influence of noise. In intelligent fault diagnosis, unprocessed signals will lead to weak fault characteristics and low diagnostic accuracy. To solve the above problem, a fault diagnosis method based on parameter optimization feature mode decomposition and improved deep belief networks is proposed. The feature mode decomposition is used to decompose the vibration signals. The parameter adaptation of feature mode decomposition is implemented by improved whale optimization algorithm including Levy flight strategy and adaptive weight. The selection of activation function and parameters is More >
