Prerequisites
Concepts of statics and structural mechanics, as well as properties of the main classes of materials used in the Civil and Environmental Engineering are assumed to be known. Furthermore, the ability to understand and produce a technical drawing is consi

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course aims to provide the student with the basic theoretical knowledge and practical skills required to design and assess reinforced concrete structures through lectures and designing exercises. Starting from the knowledge gained from basic courses, and specifically from the course of structural mechanics, students learn the structural conception, analysis methodologies and the professional aspects of structural design.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
In order to successfully solve problems relevant to the design of reinforced concrete structures, the student must gain critical judgment skills of typical engineering problems as well as the capability to solve the problems using methods, techniques and tools provided within the course. These skills are developed through lectures and tutorials that require an active collaboration with the teacher.
TRANSVERSAL SKILLS:
Designing exercises of simple structural elements, involving a critical review of several solutions, help improving the student’s critical judgment skill, as well as the self-learning skill.

Program
Contents of lectures (60 hours) Structural safety and design criteria: the method of partial safety factors (limit state design) and brief review of the working stress design approach. Actions on structures: permanent loads and live loads (of anthropogenic or environmental origin). Properties of concrete and of steel reinforcements: constitutive models; compressive and tensile strengths for concrete and reinforcements, creep and shrinkage of concrete. Behaviour of reinforced concrete elements: uncracked phase (stage I), cracked phase (stage II) and at failure (stage III); analysis methods. Ultimate limit states: columns subjected to axial force and to axial force and uniaxial bending; beams subjected to flexural, shear and torsional actions; punching shear strength. Seriviceability limit states: design at service conditions: cracks formation and openings; limits on the stress state and on deformations. Design with strut & tie models. Analysis and design of surface foundations and fundamentals of the design of deep foundations. Classroom tutorials (12 hours) Structural sizing, analysis, design and verification of a reinforced concrete slab, a balcony and a stair.

Development of the examination
LEARNING EVALUATION METHODS
The assessment of student learning is based on two tests: - a written test concerning the design of a reinforced concrete structure; - an oral assessment, consisting in the discussion of both the developed exercises and the written test, and in some theoretical questions on the topics covered during the course. The latter may also be in written form (if required by the presence of formulas or demonstrations), followed by an oral discussion. To access the oral examination, the student must have completed the proposed exercises and obtained a sufficient evaluation in the written test. The written and oral examinations must be sustained in the same examination session.

LEARNING EVALUATION CRITERIA
Through the presented exercises, the written and the oral assessments, the student must demonstrate to have learned the topics covered during the course and to be able to present them correctly, by adopting a proper technical terminology.

LEARNING MEASUREMENT CRITERIA
The evaluation of each test is expressed in thirtieths.

FINAL MARK ALLOCATION CRITERIA
After the oral examination, a final mark is defined for the presented exercises and for the written and oral assessments. The student is expected to pass all tests. The final mark of the course will be calculated as the average of the marks received in each test. Summa cum laude will be awarded to students who have correctly completed all the assessments and have shown an outstanding understanding in the subject.
