The challenge of sustainability has set new goals in the design of new structures as well as in the renovation of existing buildings, with particular reference to historical masonry constructions. This is essential if we want to make human settlements safe, resilient and sustainable, and to safeguard cultural heritage, according to the goal 11 of the UN 2030 Agenda for Sustainable Development.
Regarding new constructions, it is necessary to aim to optimize the structural form; in this context, the role of unilateral structures stands out, since materials in these structures are used in the most efficient way. This opens the way to, among other things, the use of recycled materials and of new materials with low environmental impact; moreover, unilateral structures allow the reduction of the consumption of traditional or high-performance materials, and to explore the potential of digital fabrication through 3D printing. For existing buildings, on the other hand, it is a matter of combining the requirement of safeguarding with that of conservation, and therefore a matter of developing models that can efficiently represent the unilateral behavior of materials such as masonry, avoiding resorting to excessively conservative approaches, which can lead to the decision to implement consolidation interventions that are often simply unnecessary. To achieve these objectives, an essential prerequisite is the study of the static, kinematic and dynamic behavior of unilateral structures, and the development of specific experimental approaches for the characterization of materials, the calibration of the parameters required by structural models, and the development of protocols for periodic assessment of their “structural health”.
This Special Issue, therefore, aims to collect scientific reference contributions on the behavior of unilateral structures, including theoretical and numerical modeling under static and dynamic load conditions, on the use of innovative and sustainable materials for their construction, on the use of new technologies for the construction and for the fabrication of structural elements and on the associated experimental methods ranging from the scale of the material to that of the structure.
