Learning objectives
Knowledge and understanding:
Knowledge of the mechanical behavior of concrete structures and theoretical models to describe them.
Knowledge of code rules (Eurocode2) for the design of reinforced concrete structures. Knowledge of the detailing and arrangement of reinforcement in the main structural elements.
Skills:
Ability to choose, arrange and pre-design the different structural elements that constitute a simple reinforced concrete building. Ability to write the report and to draw the reinforcements.
Making judgments:
The student must be able to choose and set the proper dimensions of structural elements
Communication skills:
During the course the student should improve his technical dictionary.
Learning skills:
The student must acquire the ability to select the most appropriate design choices also considering options that are not perfectly identical to those given during the course. He will also be able to consult the main reference books of the field
Prerequisites
Basical concepts on stress analysis and strength of materials are useful
Course unit content
Theoretical aspects and practice for the design of reinforced concrete structures and prestressed concrete structures (axial load, bending, shear, torsion, serviceability limit states, prestressed concrete structures, strut&tie for the analysis of corbels, foundations and walls). Design of a RC building (beam, column, slabs, stairs, balconies)

Teaching methods
Frontal theoretical lectures and seminars given by renowned professional egineers/professor.
Assessment methods and criteria
The exam is oral. The development of an exercise (without numerical values but only literal) and two theoretical questions on the syllabus are requested.
The duration of the oral is about one hour.
The type of exercises corresponds to the exercises done in class. The theoretical questions, on the other hand, will be on the topics of the syllabus.
The following elements will contribute to the determination of the judgment:
Knowledge of the topics covered in the course (40%)
Skills: ability to solve an exercise similar to those carried out in class (50%)
Communication skills: property of language (10%)
Praise is awarded in the case of achieving the highest score in the three questions to which is added the excellent mastery of disciplinary vocabulary.
