Nicola CosentinoLearning outcomes
The course aims to provide the main tools, methodologies and an appropriate approach in the safety assessment and design of interventions on existing buildings.
Expected learning outcomes
The development of the ability of the students to identify the expected structural behavior of a building is expected, with the aim of giving practical implementation to the regulatory dictate that characterizes existing buildings: "In existing buildings the situations that can be concretely found are the most diverse and it is therefore impossible to foresee specific rules for all cases. Consequently, the model for the safety assessment must be defined and justified by the designer, case by case, in relation to the expected structural behavior..." (§ 8.5 NTC).
Course contents
SLU and SLE checks of recurring elements (masonry, reinforced concrete, steel, wood): reminders of aspects common to new constructions and peculiarities of existing constructions.
Actions on buildings: anthropogenic, natural non-seismic, seismic action: peculiarities of existing buildings.
Masonry constructions: analysis of the effects of vertical loads; seismic analysis of global mechanisms; seismic analysis of local mechanisms.
RC and steel constructions: analysis of the effects of vertical loads; seismic analysis of global mechanisms.
Introduction to the historical-critical analysis of buildings, with particular attention to the most common construction and structural technologies.
Geometric survey, structural survey; techniques and precautions for structural survey; knowledge of construction details.
Mechanical characterization of materials: types of investigations, basic physical principles; definition, execution, potential and limits of the various available investigation techniques. The interpretation of the tests.
Knowledge levels and confidence factors: regulations and applications.
Classification of interventions; main intervention techniques; capacity models for reinforcements.
Typical problems of mixed buildings: survey, modeling and interventions.
Typical problems of building aggregates: survey, modeling and interventions.
The role of non-structural elements in safety assessment.
Critical reading of current national and international regulations and of the main technical references.
Contents of the "technical report"; explanatory graphics; content and purpose of the "final report". Problems related to the "management" of results.
Prerequisites
There are no prerequisites or prerequisites. However, prior attendance at the basic structural courses is recommended.
Reading/Bibliography
Handouts, standards and technical literature in the sector.
Teaching methods
The lessons include both the development of theoretical elements and practical-professional examples. The use of slides and the aid of information and communication technologies is foreseen. The teaching program was developed assuming in-person teaching activities.
Assessment methods
The final exam is conducted through an oral test according to the provisions of the academic calendar. The verification of the level of learning achieved by the students is also carried out through short applications/exercises relating to the concepts covered, carried out collegially in the classroom during the lessons.
