Objectives

JUSTIFICATION:
The Course Unit introduces the fundamental principles and the basis for the design of reinforced concrete elements (tension members, columns and beams). Scientific and technical aspects of the analysis and design of reinforced concrete structures are discussed, according to european standards (Eurocodes). These subjects, very relevant to the formation of a civil engineer, are essential for the professional activity in the areas of design, and management and control of construction.

OBJECTIVES:
Presentation of the principles, theories and models for the analysis and design of structural concrete elements. To analyze the behaviour of both reinforced concrete and prestressed concrete elements, either in the elastic range or close to failure. Application of the provisions of Eurocode 2 concerning the structural concrete. Initiation of students to the practice of structural design of reinforced and prestressed isostatic concrete elements.

Learning outcomes and competences

SKILLS AND LEARNING OUTCOMES:

Knowledge: To describe the principles, theories and models suitable for the analysis and design of reinforced and prestressed concrete members.

Comprehension: Understanding the behaviour of reinforced and prestressed concrete elements, both under service conditions (linear-elastic behaviour) and close to failure (nonlinear behaviour). Interpretation and application of the Eurocode 2 rules to the analysis and design of structural concrete elements.

Application: To develop solutions for the appropriate design of isostatic reinforced and prestressed concrete elements, by applying the provisions of national regulations and of Eurocode 2. Elaboration of drawings for the correct construction of the designed elements.

Evaluation: Development of criticism in regards to the obtained solutions. Choice of safe structural solutions with the best cost/performance ratio.

Research in Civil Engineering: Development of interest in knowledge discovery, by working on Civil Engineering problems without unique solutions. Stimulation of critical thinking and creativity, seeking for improved solutions for structural concrete elements.

Civil Engineering Project: Initiation of the students to the design of reinforced and prestressed concrete members.

Civil Engineering Practice: Development of appropriate and feasible solutions for reinforced and prestressed concrete members. Presentation of solutions in drawings, including all the necessary information for proper execution.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Teaching methods and learning activities

All subjects are presented and discussed during theoretical classes, where the theories and models are explained and elucidative exercises are solved. Practical classes are dedicated to the discussion of the proposed exercises, and to clarification of the student doubts.

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:
Students are encouraged to:
- Develop solutions for the appropriate design of isostatic reinforced and prestressed concrete elements, by applying the provisions of national regulations and of Eurocode 2;
- Elaborate drawings for the correct construction of the designed elements;
- Develop criticism in regards to the obtained solutions;
- Choose safe structural solutions with the best cost/performance ratio;
- Develop interest in knowledge discovery, by working on Civil Engineering problems without unique solutions;
- Stimulation of critical thinking and creativity, seeking for improved solutions for structural concrete elements.

Evaluation Type

Distributed evaluation with final exam

Assessment Components

Designation	Weight (%)
Exame	75,00
Trabalho escrito	25,00
Total:	100,00

Eligibility for exams

Achieving final classification requires compliance with attendance at the course unit, according to the MIEC assessment rules. It is considered that students meet the attendance requirements if, having been regularly enrolled, the number of absences of 25% for each of the classes’ types is not exceeded.

Calculation formula of final grade

The final grade is defined with basis on a distributed evaluation (which is compulsory) and a final exam.

The distributed evaluation consists of two tests to be held during the semester. On each of the tests every student has to submit the complete resolution of a specific exercise from the set of Exercise Sheets addressed in practical classes. That specific exercise will be indicated only during the distributed evaluation test. In addition to the submission of this exercise - solved by each student during the semester – it will be also requested the resolution of a variant of that exercise, which will have to be solved during the test, with free consultation of all elements of study.

All the evaluation components are expressed on a 0-to-20 numerical scale.

The final grade, FG, is obtained with the following formula:

FG = 0.10 x CDE1 + 0.15 x CDE2 + 0.75 x FE

CDE1 – classification of distributed evaluation test 1;
CDE2 – classification of distributed evaluation test 2;
FE – classification of the final exam obtained on the “Época Normal” and/or the “Época de Recurso”.

NOTE 1: The distributed evaluation tests are compulsory. Thus, non-fulfilment of any of them will imply a zero rating on the corresponding component CDE1 or CDE2. Students should avoid these situations, solving regularly the Exercise Sheets proposed during the semester, and attending the distributed evaluation tests on the dates advertised in due course.

NOTE 2: All students enrolled in the course unit are classified according to this method. Students with special statutes dispensing them from practical classes will have to solve the Exercise Sheets autonomously, attending to the distributed evaluation tests under the same conditions as other students.

NOTE 3: Students who might not attend any of the distributed evaluation tests, for reasons duly justified and accepted by the Director of the MIEC, will have access to alternative tests of the same nature, which will be advertised during the semester.

NOTE 4: Students who have attended the course unit in previous scholar years cannot recover their distributed evaluation classifications.
