LEARNING OUTCOMES

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).
