Special Issue Information

Dear Colleagues,

Unreinforced masonry constitutes one of the most common structural typologies in Western and Eastern architecture, and it largely prevails in many of the historical buildings worldwide, including monumental constructions and other buildings of relevant artistic significance in regard to world cultural heritage. Masonry is also significantly widespread among ancient infrastructures such as historical bridges and tunnels. Due to aging, changing loading demands, weathering, vibrations due to earthquakes and anthropogenic events, and many other factors, masonry structures often show significant signs of deterioration and distress, and the long-term performance of such assets is affected by high uncertainty. Structural failures in masonry-built environments would lead to uncountable direct and indirect economical and social losses, and an inestimable value is therefore at stake. Hence, there currently is an urgent need to better understand both the in-service and ultimate structural behavior of masonry structures under the action of both static and dynamic loading. To this aim, the effective and reliable structural assessment of new and historical masonry structures requires, on the one hand, in-depth knowledge of their current state by properly surveying actual geometries, restraint and loading conditions, and pre-existing damage, as well as the testing and of materials’ mechanical properties. On the other hand, the development of novel advanced mechanical models and accurate and efficient numerical techniques is strongly needed in order to predict the structural behavior of complex masonry structures under both service and exceptional loadings, such as earthquakes. Such models should precisely account for the strongly nonlinear compression-only mechanical behavior of masonry and different sources of uncertainty that can affect material mechanical properties and composition.

This Special Issue welcomes contributions that advance the state of the art of the aforementioned topics, including, but not limited to, the following topics:

  • Analytical and computational strategies for the assessment of the most common masonry structural systems such as walls, arches, vaults, and bridges.
  • Numerical approaches for the analysis of masonry buildings undergoing earthquakes and other dynamical loadings.
  • Standard and non-standard limit analysis of masonry structures.
  • Rigid block models for masonry structures.
  • Analytical and computational strategies for the repair and retrofitting of masonry structures.
  • Soil–structure interaction for masonry structures.
  • Dynamic or static, as well as in situ or laboratory, testing of masonry structures.
  • Full-scale tests on structures.
  • Fragility assessment of masonry structures.
  • Vulnerability assessments of the masonry-built environment at the regional scale.

Stress state evaluation in axially loaded structural members is significant for sustaining and preserving the service life of buildings. While successful monitoring furnishes staunch information on the health, integrity, safety and serviceability of structures, maintaining the structural performance of a building with time significantly depends on assessing the occurrence. Variations in the stress in axially loaded members may occur in masonry buildings or space structures caused by different conditions and human-induced factors. In the last decades, numerous nondestructive methods have been generated to furnish practical means for identifying axial load in the tie-rods of masonry buildings and in the structural members of space structures. Significant effort has been put into dynamic-based approaches, which make use of the vibrational response of the monitored member to investigate its condition and evaluate the axial load. In particular, wide laboratory and field tests have been executed worldwide, resulting in several findings. Meanwhile, with flourishing sensing technology and computing power, Artificial Intelligence (AI) applications, such as hybrid methods, optimization techniques and deep learning algorithms, have become more practicable and widely used in vibration-based axial stress prediction, with efficiency and, frequently, with strict precision. While there have been various manuscripts published on dynamic-based axial stress evaluation, there are no works in which the passage from traditional methods to combinations with AI approaches have been illustrated. This article aims to address this gap by introducing the highlights of the traditional methods, and furnish a review of the applications of AI techniques used for nondestructive-based axial stress prediction in tie-rods and structural members. Conclusions, including further studies and field developments, have also been mentioned at the end of the article. Full article

This research concerns the introduction and the structural analysis of masonry vaults in Puglia, a region in the south part of Italy, built between the sixteenth and the seventeen centuries. Such vaults have special shapes that make them unique in the overview of the masonry vaults spread all over the world. The present paper intends to shed light on the mechanical behavior of two typical vaults in Puglia, the “volta a spigoli” (edge vault) and the “volta a squadro” (square vault). There are many contributions that explore the mechanical behavior of the classical vaults, but to the authors’ knowledge, this is the first attempt investigating the “volta a squadro”. The paper describes the adopted research methods. First, a building survey is carried out with the integration of previous geometry acquisitions performed by local stakeholders. Then, the analysis is pursued by a non-linear approach that suitably inserts cracks where stress concentrations occur. Two meaningful load conditions are taken into account and numerically investigated. Under vertical loads, numerical results have inferred the surveyed cracks and concluded that the safety factor is much higher than one. On the other hand, under the maximum seismic load, the safety factor is estimated to be about 30%. This work is the very first investigation on the structural performance of a “volta a squadro”.
