Highlights
  • A comprehensive review of the existing geometric measures for irregular masonry patterns, highlighting the gaps and possible future trends, is presented.
  • Masonry pattern generator algorithms enable the systematic study of masonry pattern quality. Therefore, the importance of implementing proper digital tools to generate masonry specimens with consistent QI-s, is underlined.
  • A numerical investigation underlines how masonry textures generated considering quality indexes present more consistent results.
  • Robust probabilistic approaches should be developed, accounting for limited knowledge of the structure under investigation.
ABSTRACT

While the influence of the component strength on the structural behaviour of Historic Masonry Structures (HMS)
is relatively well studied, few studies have investigated masonry textures. Such a research gap is due to the actual
difficulty of finding parameters that correlate masonry patterns and structural performances. This paper presents
a comprehensive review of the existing geometric measures for irregular masonry patterns, highlighting the gaps
and possible future trends. Special attention is paid to the Non-destructive Tests (NDT) for surveying masonry
textures and algorithms to generate block-based numerical models artificially. Finally, a numerical investigation
underlines how masonry textures generated considering quality indexes present more consistent results.
