The course aims to illustrate the criteria to be adopted in the strengthening of existing buildings, highlighting the different approach that must be followed with respect to the design of a new structure. In particular, the design choices must derive from adequate knowledge and diagnosis (learned in more detail during the "Structural assessment and safety of existing buildings") and must have a clear objective in terms of performance. The different techniques available will then be illustrated, with reference to both masonry and reinforced concrete buildings.
Classification of structural retrofitting interventions on existing buildings: maintenance, damage repair, local interventions, overall strengthening. Strategies for the choice of interventions: force versus deformation capacity, reversibility, durability, cost-benefit analysis. From the diagnosis to the design of interventions (monitoring, provisional works). Conceptual classification of strengthening techniques: traditional solutions versus use of innovative materials. Masonry buildings: foundations; masonry walls (cracks repair, widespread strengthening, improvement of connections); arches and vaults; floors and roof (bending strengthening, diaphragm effect); local interventions (creation of new openings or framing of existing ones); seismic improvement. Reinforced concrete structures: restoration of concrete; reinforcement of elements and nodes with composite materials; dissipative bracings; selective weakening and use fuse (elements of sacrifice).
