Structural Concrete

Strength of materials, reinforced concrete I and II, and analysis of structures

Theoretical-practical lessons of exposition; resolution of exercises; discussion (change ideas); oral and written report presentation.
Evaluation: research work with presentation and discussion (5 points and it is optional). This work can be done individually or in group (maximum of 2 students) and must be submitted with the format specified by the teacher. Written exam to be carried out during the period of exams.
The student can choose not to do the research work or can do the research work and choose not to account for the final result. In these cases, the final exam will be quoted for 20 points. For the student who chooses to account research work for the final result, the final exam will be quoted for 15 points.
The approval requires the achievement of at least 9.5 in the final result and the minimum of 7 points (in the range of 0 to 15) in the written exam (for the students who choose to consider the evaluation of the research work in the final result).

Objectives: Learn the theory and the practice related with the design and manufactured of reinforced and prestressed concrete structures.
Generic skills: Application of knowledge and understanding; Judgment accomplishment and decision making; Communication; Self learning;
Specific skills: Acquire knowledge and understanding capacity in the field of reinforced concrete structures (buildings and bridges usually used in the urban space), particularly at the level of design and manufacturing; review the fundamental principles on the behavior of reinforced concrete structures in order to strengthen the knowledge already acquired; increase the capacity to understand the reinforced concrete structures used in the urban space; provide the students with new knowledge to deal with complex and contemporary situations in the area of reinforced concrete structures (making judgments and developing solutions).

1. Serviceability Limit States: cracking; calculation of crack widths; control of cracking without calculations; minimum reinforcement areas; limits recommended by codes for vertical displacements; general considerations and deflection control, checking the deflection limit state with direct calculations and without direct calculation.
2. Flat slabs: structural analysis – calculation of the distribution of internal forces and design.
3. Structural analysis: linear analysis with limited redistribution and plastic analysis for beams and slabs (ductility and plastic rotation capacity)
4. Prestressed concrete: structural interest of prestressing; precast concrete elements; prestress force; immediate losses of prestress for pre-tensioning and post-tensioning; time dependent losses of prestress; determination of the prestress force; layout of the prestress cable; checking the safety to the ultimate limit states (bending moment and shear); anchorage of pre and post-tensioned tendons.
