Masonry vaults are able to withstand their dead load and external forces thanks to their curved surface, therefore geometry plays a major role in their structural behaviour. Besides the well-known effects of the macro-geometry (overall shape and dimensions), micro-geometry (details of the masonry apparatus) is also expected to play a key role. The study seeks to determine the advantages (constructional and structural) that a specific masonry apparatus offered for simple forms like barrel vaults and more complex forms like cross vaults. It is carried out, firstly, through a critical review of the European technical literature concerning vault construction with particular focus on brick laying techniques; then, numerical approach is adopted to scientifically investigate the role of micro-geometry on the static behaviour of barrel and cross vaults subjected to self-weight. Comparison of results allows observing different structural behaviour (displacement field, elastic stiffness, reaction forces) for different brick patterns and provides a scientific validation to some speculations found in historical technical literature.
