Special Issue Information

Dear Colleagues,

Civil structures and infrastructures may suffer damage due to the action of natural hazards, (e.g., earthquakes, strong winds), other mechanical degradation phenomena (e.g., fatigue, corrosion), and their synergistic effects. Data-driven SHM techniques have emerged as valuable tools to monitor the health of a structure, enabling the identification of damage and plan repair operations and thus guaranteeing life safety and functionality.

Traditionally, SHM systems involve the on-site integration of dynamic and static sensors, along with data acquisition systems to continuously record information of different nature. Such information can be subjected to a large amount of uncertainty due to the inherent complexity of the structural systems and environmental disturbances (e.g., noise).

Although SHM is a growing area, research efforts are still needed to generate probabilistic frameworks based on automated numerical tools capable of managing different sources of uncertainties, and to comprehensively address the five-step hierarchy of a damage identification process: (i) detection, (ii) localization, (iii) classification, (iv) assessment, and (v) prediction.

This Special Issue invites high-quality contributions that address the investigation of the current state of the art, recent advances, real-world applications, as well as future perspectives in SHM for structures and infrastructures, including the following topics:

  • State-of-the-art reviews and novel contributions in probabilistic-based SHM techniques for structures and infrastructures;
  • Recent advances in SHM technologies;
  • Machine learning applications;
  • Novel methods on data fusion;
  • Recent developments in Bayesian-based techniques as decision-support tools for the evaluation of structural integrity;
  • The use of surrogate modeling for automated damage identification;
  • Application of lifecycle cost analysis for reducing SHM-related operational costs and risks.

To date, the application of composite materials has been used throughout the globe due to its advantages, such as corrosion resistance, high strength, design flexibility, and light weight. However, the joining of composite materials is usually achieved with adhesives, where debonding of parts can cause unexpected failure. Thus, detecting and locating defects due to impact or fatigue stresses at an early stage is crucial to ensure safety. Various non-destructive testing (NDT) techniques have been used to detect defects in composite structures, where this study proposes an improved approach of using one of the NDT techniques to detect and locate debonding of glass fiber epoxy plates. Here, the electromechanical impedance (EMI) technique is used with a new way of detecting defects using a movable device. This idea could reduce the overall cost of the monitoring system as the conventional EMI technique requires one to permanently attach a large number of piezoelectric transducers when monitoring large structures. The performance of the proposed idea is tested against another temporary attachment method to investigate the possibility of using the new idea for monitoring debonding in composite structures.
