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.

Teaching methods and learning activities

All subjects are presented and discussed during theoretical classes, where the theories and models are explained. 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.

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 consists of two tests to be held during the semester. All the evaluation components are expressed on a 0-to-20 numerical scale.

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

FG = 0.40 x CDE1 + 0.60 x CDE2

where:
CDE1 – classification on the test of Distributed Evaluation 1 (to be performed during the "Semana da FEUP");
CDE2 – classification on the test of Distributed Evaluation 2 (to be performed during the period of examinations "Época Normal”).

NOTE 1: The tests of Distributed Evaluations 1 and 2 are compulsory. If the student is not present at any of these tests, or if intends to improve the corresponding classifications, then the student must apply to the "Recurso" examination defined on the examination period.

NOTE 2: In the "Recurso" examination the student may opt for being evaluated on the program subjects: (i) just related to CDE1, (ii) just related to CDE2, or (iii) concerning all the program matters. For cases (i) and (ii) FG will be obtained using the formula defined above, considering for CDE1 and CDE2 the best classifications obtained by the student on the Distributed Evaluations and on the "Recurso" examination. For the student who has selected option (iii) the final grade FG will be the classification on the "Recurso" examination, or the FG classification which results from the formula above if the latter is superior and the student has performed both Distributed Evaluations.

NOTE 3: All students enrolled in the course unit are classified according to this method.

NOTE 4: Classifications from Distributed Evaluations obtained in previous scholar years are not applicable to the present scholar year.

NOTE 5: Students who wish to obtain a final grade over 17 must have a final grade FG not less than 17.5 and apply for an oral exam.
