Objectives

JUSTIFICATION:
The Course Unit (CU), included in the group of CUs of the 2nd semester of the 4th year, complements the knowledge on the structural concrete area initiated at the CU Structural Concrete 1. 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:
To present the principles, theories and models for the analysis and design of reinforced concrete structures. To analyse the behaviour of reinforced 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 structures of reinforced concrete buildings.

Learning outcomes and competences

SKILLS AND LEARNING OUTCOMES:

Knowledge: To describe the principles, theories and models suitable for the analysis and design of reinforced concrete structures, including linear elements (beams and columns), laminate elements (slabs and bracing shear walls) and foundations.

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 structures of reinforced concrete buildings, 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 structures of reinforced concrete buildings.

Civil Engineering Practice: Development of appropriate and feasible solutions for reinforced 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 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 structures of reinforced concrete buildings, by applying the provisions of national regulations and of Eurocode 2. Elaboration of drawings for the correct construction of the designed elements. Development of criticism in regards to the obtained solutions. Choice of safe structural solutions with the best cost/performance ratio. Development of interest in the discovery of knowledge, by working on Civil Engineering problems without unique solutions.

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 consists of two written evaluations performed during the theoretical classes - and a final exam. (The distributed evaluation is optional). All the evaluation components are expressed on a 0-to-20 numerical scale.

The final grade, FG, is obtained with the following formula:
FG = max {CT ; FE}

where,
CT = PA / 2 x CAD1 + PA / 2 x CAD2 + PF x FE

CAD1 – classification of the written evaluation 1 performed during a theoretical class;
CAD2 – classification of the written evaluation 2 performed during a theoretical class;
FE – classification of the final exam obtained on the “Época Normal” and/or the “Época de Recurso”.

The classifications CAD1, CAD2 and FE are associated with the following weighting factors:
PA = 25%
PF = 75%

NOTE 1: The written evaluations, associated to the classifications CAD1 and CAD2, are optional. If the student does not obtain any of these classifications, the respective weight is added to PF.

NOTE 2: All the students registered on the unit course are classified according to this method.

NOTE 3: Students registered on the unit course in the scholar year 2013-14 may keep the corresponding distributed evaluation. In that case, the weights to be used are the ones indicated on the scholar year of 2013-14.

Observations

PREVIOUS KNOWLEDGE:

The non-attendance and/or approval in the course units of Strength of Materials, Mechanics, Structural Analysis and Structural Concrete 1 will create great difficulties in learning the present Course Unit.
