Special Issue Information

Dear Colleagues,

This Special Issue aims to highlight the latest advancements in civil structure-related nondestructive testing (NDT) and diagnostics. It will showcase innovative technologies and applications that facilitate the accurate and efficient monitoring, evaluation, and condition assessment of civil infrastructure systems.

This Special Issue focuses on NDT methods, advanced diagnostics techniques, and their applications in civil structures, with its scope including, but not limited to, the following topics:

  • Nondestructive testing methods for assessing the condition of concrete, steel, and wooden structures;
  • Innovative signal processing techniques for enhancing the reliability and accuracy of NDT data;
  • Integration of NDT data with numerical models for structural health monitoring and prognosis;
  • Case studies demonstrating the practical application of NDT techniques in civil structures;
  • Development of automated and semi-automated NDT systems for efficient data collection and analysis;
  • Use of NDT data for decision-making in maintenance, repair, and replacement of civil infrastructure elements;
  • Challenges and future trends in NDT for civil structures.

Prestressed steel strands in prestressed structures offset or reduce the tensile stress caused by external loads, making them the primary load-bearing components. Great concerns have been raised about prestress monitoring due to the growing use of structural health monitoring (SHM). Piezoceramic (PZT) active sensing methods are commonly used in this field. However, there appears to be a problem of “energy saturation” in the utilization of piezoceramic active sensing methods. In this study, a smart anchor washer with semi-cylinders was developed to alleviate the saturation problem. An intelligent monitoring system is formed by combining the upper and lower annular cylinders with two piezoelectric patches. The piezoelectric patch on the upper annular cylinder is used as an actuator to emit signals through the contact interface of the smart anchor washer, which are then received by the piezoelectric patch on the lower annular cylinder. Based on wavelet packet decomposition, we investigate the correlation between the energy of the received signal and the applied tension force. Finally, a prestressing force index is developed for monitoring prestressing force using Shannon entropy. It is found that the index decreases with the increase in tension. The proposed design and index are also sensitive to early monitoring of prestressing force and can be used to monitor the entire prestressing process of steel strands. Full article
