Special Issue Information

Dear Colleagues,

Civil structures and infrastructures are susceptible to damage caused by natural hazards and extreme events such as earthquakes, strong winds and flooding, as well as material degradation and increasing traffic actions. Data-driven structural health monitoring (SHM) techniques have emerged as valuable tools for assessing the current structural state of conservation. Additionally, model-based approaches can provide support, both in identifying damage and in planning repair operations, as well as in properly managing the limited funding for maintenance interventions, thereby ensuring the safety and functionality of structures and infrastructures.

Traditionally, SHM systems involve the installation of dynamic and static sensors on-site, along with data acquisition systems to record various types of information over time. However, these data can be highly uncertain due to the complexity of structural systems and the influence of external factors like environmental noise (i.e., temperature, relative humidity, etc.).

In this context, SHM is a growing field, although there is still the need for research efforts to create probabilistic frameworks using automated numerical tools that can handle various sources of uncertainties. Additionally, it is of paramount importance to address the topic of damage identification, which also includes detection, localization, classification, assessment, and, above all, the prediction of its evolution.

This Special Issue aims to highlight and discuss new developments, inviting high-quality contributions that focus on the investigation of the current state-of-the-art, recent advancements, practical applications, and future perspectives in SHM for structures and infrastructures. The contributions can cover the following topics:

  • In-depth reviews and innovative contributions in probabilistic-based SHM techniques for structures and infrastructures.
  • Recent developments in probabilistic-based techniques as decision-support tools for evaluating structural integrity.
  • Recent advancements in SHM technologies.
  • Novel methods for data fusion.
  • The use of surrogate modeling for automated damage identification.
  • The application of life-cycle cost analysis to reduce operational costs and risks associated with SHM.

In this paper, concrete cracking is investigated in dynamics through finite element modeling. A probabilistic semi-explicit model, previously developed and validated for static loading, is extended for dynamic loading. The model in statics is based on two material mechanical parameters: the tensile strength and the critical strain-energy release rate in mode I, GIC, of the Linear Elastic Fracture Mechanics (LEFM) theory. Concerning the dynamic aspects of the model, the tensile strength rate effect is modeled by an empirical dynamic-to-static strength ratio (Dynamic Increase Factor—DIF) and a similar formulation is proposed for GIC. The structural rate effect is naturally captured when mass and damping are included in the equation of motion. For static and dynamic loading, only macroscopic crack propagation is considered. Some numerical simulations in statics and dynamics are presented in the present paper. The main results related to this work can be summarized as follows: the dispersion of the numerical results related to the load–displacement curves decreases with the loading rate. The crack pattern considerably changes with loading rate (numerically and experimentally); the agreement between the experimental and numerical results (load–displacement curves and crack pattern) indicates the model is promising for engineering applications.

This paper introduces a three-dimensional (3D) semi-explicit probabilistic numerical model for simulating crack propagation within the framework of the finite element method. The model specifically addresses macrocrack propagation using linear volume elements. The criteria governing the macrocrack propagation is based on the softening behavior observed in concrete under uniaxial tension. This softening behavior corresponds to a dissipated cracking energy that is equal to the mode I critical fracture energy (GIC) used in the Linear Elastic Fracture Mechanics theory (LEFM). The probabilistic nature of this model revolves around the random distribution of two mechanical properties: tensile strength (ft) and fracture energy, which varies based on the volume of finite elements. The scattering of the fracture energy increases as the volume of finite elements decreases in order to consider the strong heterogeneity of the material. This work primarily aims to estimate the relationship between the standard deviation of GIC and the volume of finite elements through the development of the numerical model. For this purpose, an inverse analysis is conducted based on a fracture mechanical test simulation. This test involves macrocrack propagation in a large Double Cantilever Beam (DCB) specimen with a crack length exceeding two meters. The proposed inverse analysis procedure yields highly significant results, indicating that the numerical model effectively evaluates both crack length and crack opening during propagation.
