ASSESSMENT OF STRUCTURAL SAFETY
Learning outcomes of the course unit
-Knowledge and ability to understand:
At the end of the course, the student must have acquired a broad and critical point of view of methods and techniques for the knowledge of the historical and architectural heritage and its state of conservation, as well as tools for restoration and consolidation, in relation to the existing cultural debate. The knowledge acquired, also from the point of view of structural behaviour, must allow the student to correctly deal with the analysis of the current state of the existing structure and to design the interventions for the consolidation, making the most suitable choices also in relation to the structural pathologies and deficiencies found.
At the end of the course, the student must have developed the ability to identify and detect all the dimensional, material, structural and pathological aspects that characterize a historical building and to assume them as the founding basis of the restoration and consolidation project.
Autonomy of judgement:
Upon passing the exam, the student will have developed the ability to critically assess the state of conservation of a historic building, identifying the consolidation techniques most appropriate to the case in exam, balancing conservation, safety and functionality. He will also have acquired the ability to understand and evaluate the quality of any restoration and consolidation project.
During the course, students must refine their language skills, with specific reference to the technical terminologyof the course, in order to communicate their project effectively and accurately.
Materials and techniques for the consolidation of historical buildings are subject to continuous and rapid innovation. Therefore, the student must acquire the ability, once the problem to be solved has been identified, to select the most suitable intervention also evaluating options not necessarily exposed during the course.
It is useful to have attended the Restoration course, as the basic knowledge of restoration theory and construction characteristics of historical buildings are taken for granted in the course.
It is also useful to have attended the course of Structural Mechanics (Tecnica delle Costruzioni), as we take for granted some basic topics such as the evaluation of actions on buildings and the design of structural elements.
Finally, it is useful to have knowledge of CAD programs (Autocad type), spreadsheets (Excel type) and multimedia presentations (e.g. Powerpoint).
Course contents summary
The course analyzes the structural behavior of existing masonry buildings of historical interest.
In particular, the course provides to the students the tools for the analysis and assessment of the main structural elements of an existing building, that is:
- the walls (with particular reference to their out-of-plane behaviour, both in the presence of static and seismic actions)
- arches and lintels,
-vaults and domes
- the elements of a timber roof
- the timber trusses.
The main differences with respect to the design of new buildings will also be highlighted, also in relation to the Knowledge Level achieved.
The concepts analyzed from the theoretical point of view will then be applied by the students during a design exercise related to the restoration and consolidation of an existing historical building.

The course consists of a series of frontal lessons, also with the help of Powerpoint presentations, and reviews of the project.
For the project, students will be divided into groups of 2-4 people, Each group will develop the project of restoration and consolidation of a historic building and will be followed by the teacher through a series of revisions during the course. The reviews are carried out in groups by analysing the material printed on paper by the students.
Assessment methods and criteria
During the year, reviews are planned with the teachers to verify the project. These intermediate moments of audit, although they have no direct connection with the final mark, are still essential to demonstrate the successful attendance of the course.
The module does not have a separate evaluation, but the verification is part of the overall final examination of the integrated course of "Analysis and conservation of existing structures."
The examination will take place individually in oral form and will consist of:
1) discussion of the project (50%), which must be given to the teachers before the exam date
2. oral examination on the entire programme carried out during the year, relating to:
- theoretical part of consolidation (Restoration and Consolidation module): 25% of the total mark;
- Theoretical part of the structural safety assessment (Structural safety assessment module): 25% of the total mark.
