Educational objectives	The module illustrates the dynamic and static, linear and non linear, methods of seismic analysis; the seismic-resistant structural schemes; the code provisions for constructions in seismic areas; the construction details of r/c elements. A specific teaching unit is devoted to develop a guided and assisted assessment of an existing structure or the design of a new structure. The expected learning outcomes are listed in the following. The main acquired knowledge will be: • knowledge of the methods for the analysis of structures subjected to earthquakes; • knowledge of the behavior of basic structural schemes for the resistance to lateral actions; • knowledge of prescriptions of Italian and European codes concerning general aspects and detailing in the design of r/c seismo-resistant costructions; • knowledge of the basic principles of the seismic protection of structures (resistance, redundancy, resilience, ductility, capacity design). The main acquired skills, intended as abilities to apply knowledge and to critically adopt the most appropriate approach, will be: • ability to select and apply the appropriate approach for the assessment of the consequences of the seismic action on a construction, with awareness of the significance and the values of the involved parameters and the quantities ; • ability to select and apply a behavior model of a structural scheme aimed at interpreting the seismic-resistant capacity of the structure with reference to the performance expectations in the event of an earthquake; • ability to select and apply the provisions of the relevant codes in the design of a construction in earthquake prone area and to translate them into construction configurations of detail; • ability to choose and design a suitable seismic-resistant structural system for the seismic safety of a construction.
Prerequisites	For the comprehension of the contents of the course and for the achievement of the provided educational objectives the following knowledge are required: •Mathematical Analysis: derivation and integration techniques; elementary differential equations. •Physics and Analytical Mechanics: vector calculus; equilibrium equations. •Strength of Materials and Structural Design: elements of strength of materials; static analysis of isostatic and hyperstatic structures (forces method and displacements method); methods of assessment of r/c elements; code prescriptions for the design and the verification of r/c elements.
Teaching methods	Theoretical lessons and practical training
Learning verification modality	The verification of the educational objectives of the course is based on an oral exam. Within the oral exam the student will also illustrate reports and drawings developed in the design laboratory (practical training). The oral exam consists of a discussion lasting no more than about 40 minutes to determine: (a) the correctness, completeness and accuracy of the document developed in the design laboratory (practical training); (b) the level of knowledge of the theoretical and methodological contents of the course; (c) the level of competence in exposing the possible technical solutions of problems concerning modeling and solution of seismic-resistant structural schemes, dimensioning and checking of structural components stressed by the effect of seismic actions in the elastic and post-elastic range; (d) the independence of judgment in proposing the most appropriate approach for each application, with the full awareness of the simplifying assumptions adopted in the different modeling of structure and seismic action, the physical meaning of the involved parameters, the level of uncertainty of the obtained results; (e) the student's ability to expose with property of language the topics proposed by the commission, to support a dialectical relationship during the discussion, and to summarize the results of application of studied theories. The final evaluation will be carried out by the Commission in thirtieths on the basis of the oral exam result.

STRUCTURAL DESIGN OF REINFORCED CONCRETE STRUCTURES

Code	A001152
CFU	6
Teacher	Marco Breccolotti
Teachers	Marco Breccolotti Andrea Meoni (Codocenza)
Hours	40 ore - Marco Breccolotti 14 ore (Codocenza) - Andrea Meoni
Learning activities	Caratterizzante
Area	Analisi e progettazione strutturale per l'architettura
Academic discipline	ICAR/09
Type of study-unit	Opzionale (Optional)
Language of instruction	Italian
Contents	The module consists of two teaching units. The first teaching unit deals with the topic of structural safety, with reference also to the current regulations on the subject. The second unit deals with the structural design of reinforced concrete structures. Classroom exercises are also planned to apply the theoretical concepts seen during the theoretical lecture hours to simple structural problems.

Educational objectives	The module aims at providing the theoretical and normative references for the use in industrial and civil constructions of structural concrete.
Prerequisites	In order to be able to understand and apply the majority of the techniques described within the Course, you must have successfully passed the Structural Mechanics and Strength of Materials exam.
Teaching methods	The module is organized as follows: - frontal lesson on all the topics of the program; - classroom exercises; - visits in precast factories and construction sites (if possible).
Other information	Additional information materials will be provided through the university's teaching platform.
Learning verification modality	The exam includes a written test and an oral test. The written test consists in performing two numerical exercises. The first concerns the steel structures and may be relevant to the verification/design of element/structural system and its bolted or welded connections. The second exercise is instead relevant to reinforced concrete structures and may be relevant to the verification/design of element/structural system. The oral exam is a discussion lasting about 45 minutes aimed at ascertaining the level of knowledge and understanding achieved by students on the theoretical and methodological implications listed in the teaching program. This trial will also test the ability of communication of the student and of autonomous organization of the exposure on the theoretical topics.
Extended program	The module consists of two teaching units and related exercises: Teaching unit I: Theoretical Fundamentals (15 hours) The methodology of structural design. Structural reliability. Types and Patterns of actions and materials. Eurocodes and Italian legislation. The measure of security in terms of forces, components of stress, tension. Teaching Unit II: Reinforced concrete structures (30 hours) Constructions made of structural concrete: materials, method of calculation; resistance checks, stability checks, practical rules for the design and execution; legislation. Exercises (9 hours) Examples of design and verification of individual structural elements and simple structural systems (frames, portals).
