Riabilitazione Strutturale (EA)
STRUCTURAL REHABILITATION Alessandro Balducci
Structural analysis and design (Tecnica delle Costruzioni).
KNOWLEDGE AND UNDERSTANDING:
The course aims to improve the knowledge of techniques for the structural rehabilitation of reinforced concrete, masonry and mixed masonry-reinforced concrete existing buildings, with particular focus on seismic issues. CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
Disciplinary knowledge gained in the framework of the structural retrofit of existing buildings makes the student able to develop adequate design and technical solutions, with reference to compatibility, environmental sustainability, requirements and possible constraints. The required skills are developed through lectures, including specific practical examples, in conjunction with an optional designing exercise carried out individually or in groups.TRANSVERSAL SKILLS:
The designing exercise helps to improve the self-learning skill, the ability to communicate results and to generalise the acquired knowledge. Furthermore, an active involvement in the teamwork is developed.
The problems of salvage and restoration.
The surveying of buildings for safety inspection and structural overhaul; geometrical and dimensional surveying; critical surveying; the investigation of decay and their explanation; material and structure inspections; foundation and terrain inspections.
Masonry buildings: the historical development of materials and masonry; typologies; the ideal masonry model; resistance criteria; masonry building design in accordance with the standards in force.
Floors: wood as a construction material; the design of wood structures; historical floors; typologies; pathologies; salvage, strengthen and retrofitting techniques.
Masonry arches and vaults: history and development; the arch and vault check; decay and salvage/strengthening techniques.
Masonry buildings in seismic areas: the ideal model of buildings capable of withstanding an earthquake; safety requirements; action and seismic combinations; global analysis methods and check criteria; local mechanism analysis methodology; techniques for improving building's seismic response and how to choose between them; the capacity model for a vulnerability evaluation and seismic retrofitting in accordance with Italian Standards (NTC 2008).
Concrete buildings in seismic areas: safety requirements; action and seismic combinations; the analysis method and check criteria; capacity models for seismic vulnerability checking and for retrofitting; traditional techniques for primary and secondary structural element retrofitting; innovative techniques for a building's seismic rehabilitation; base isolation; dissipative brace windward.
Building decay due to foundation collapse: monitoring techniques and subsidence measurement; evolution; decay analysis and their causes; retrofitting and rehabilitation techniques; typical causes.
