053328 - MECHANICS AND DESIGN OF STRUCTURES
The teaching provides students with the skills for the definition of a structural concept and the design of the elements that are part of it, based on the main construction materials nowadays used, including reinforced concrete and steel. On the other hand, the teaching will provide the knowledge to evaluate the safety level of historical building and to perform the most suitable structural strengthening of historical buildings.
The teaching will address the following topics: definition of the loads acting on the structures; beam theory and force method for the calculation of statically indeterminate structures, calculation of internal forces and stresses; design and verification of the structural elements and connections; construction historical materials and diagnostic survey; strengthening techniques.
The teaching is divided in two modules: Design of Structures; Strengthening of historical buildings.
Risultati di apprendimento attesi
After passing the exam, the student: understands the functioning of the construction systems in relation to technology and materials (wood, masonry, steel, reinforced concrete) that characterize the intervention in the built heritage; is able to select the principles useful for obtaining solutions to static problems in the intervention on built heritage; is able to manage with autonomy of judgment the problems not strictly related to the problems faced in the teaching assuming motivated decisions.
Design of Structures
The aim of this module of the teaching is to provide the skills for the design of both reinforced concrete and steel structures. Both simple structural elements and multi-storey buildings will be dealt with and the problems related to the connection of structural elements emphasized. Eurocode 2 and 3 will be adopted as reference codes for the design of reinforced concrete and steel structures, respectively.
Specifically, this module will address the following topics:
Instability of compressed members;
Concrete and steel as structural materials: mechanical material properties and their characterization;
Structural concept most adopted for reinforced concrete and steel structures;
Loads acting on the structures and their combinations;
Design of structural elements, for both reinforced concrete and steel structures, under axial, shear, bending and combined axial-shear-bending loading conditions.
Strengthening of Historical Buildings
The aim of this module is to provide advanced knowledge on the design of the Strengthening of historical buildings. To this end the first part of the course describes the main characteristics of the construction materials and of the diagnostic survey, with particular reference to both non-destructive/destructive technique and crack pattern analysis. The results of the diagnostic survey are crucial to define the proper intervention on the building. The main part of the teaching focuses on the strengthening techniques, which can be chosen depending on the building conditions evaluated with the previous diagnostic surveys.
First, the characteristics of the traditional and the new materials used for rehabilitation will be discussed. Then, the main refurbishment techniques on:
masonry buildings (walls, arches, vaults)
wood structures (floors and roofs)
reinforced concrete structures and
will be explained.
The study of the different interventions will consider also the effect of horizontal (i.e. seismic) actions.
The teaching will include theoretical lectures and practical examples.
At the end of the teaching, the student will be able to select the most suitable intervention to strengthen an historical building based on the initial structure condition.
A basic knowledge of statically determinate and indeterminate structural systems and sectional analysis is required. However, a quick recall on some basic knowledge will be provided in the teaching.
Modalità di valutazione
To pass this teaching it is necessary to pass the written final exam. In order to take part in the exam a project work, to be developed in groups of 2-3 persons, has to be approved. The final score will be the average of these two contributions.
