Main Aims/Objectives

In this curricular unit it will be taken into account that the transmission of knowledge in the field of civil engineering must be continuous and gradual throughout the course, and adjusted to the architecture course. As such, matters will be addressed that convey the knowledge necessary to understand the behavior of different structural elements, constituents of building structures, materials in the area of Static and Strength of Materials.

Specific Aims/Objectives

It is intended that students acquire knowledge that allows them to have a better understanding of the importance of structural elements, their behavior, their functioning, their location and space that they occupy in the projects they develop, thus giving continuity to the problem of Statics and the Strength of Materials, which has been addressed in other subjects of this course.

Skills to be acquired

Obtain knowledge, for students to be able to pre-design structural elements in reinforced concrete or steel, requested to bend or requested to traction, or compression, simple, obtaining the minimum order of magnitude of the dimension of these elements associated with the project under development , in order to better integrate them into the architectural project.

Teaching Procedures

This curricular unit has a weekly schooling of four hours, with two hours of formal theoretical exposition, and the other two dedicated to solving exercises and carrying out practical work, which will be integrated in continuous assessment, which will consist of the individual application knowledge acquired in a project carried out by the student.

Programme

SIMPLE TRACTION AND COMPRESSION:
- Resistance of materials (definitions and fundamental concepts).
- Axially loaded bar.
- Distribution of internal efforts.
- Normal tension.
- Linear deformation.
- Tension - deformation diagram.
- Ductile and fragile materials.
- Hooke´s law.
- Mechanical properties (proportionality limit; elasticity limit; yield limit; yield limit; strength limit; allowable stress; linear elastic behavior zone; elastic zone; plastic zone; elastic deformation; plastic deformation; zone hardening material).
- Variation of tension with the orientation of the cross section, in the case of simple traction and compression.
MESHY SYSTEMS:
- Pre-dimensioning of plane structures of meshy systems (tensioned bars; compressed bars; design values of resistant stresses in the case of metallic structures).
- Lateral contraction - Poisson´s ratio.
- Constructive dispositions of the nodes of plane structures of meshy systems (type of metal profiles; type of joints of metal profiles - direct joints, joints using plates).
- Support devices (fixed support devices; mobile support devices; elastomeric support devices).
FLEXION:
- Interior efforts (general case; particular case of a structural element, with a straight axis and constant section with a vertical symmetry axis, prompted by loads contained in a vertical plane).
- State lines (basic rules for drawing the state lines; relationship between the bending moment and the transverse effort - relationship between the drawing of the diagram of the transverse forces and the drawing of the diagram of the bending moments, relationship between the null transverse effort and the maximum or minimum bending moment, generalization of the study of the state lines in structural elements, of straight line and constant section with vertical symmetry axis, requested by loads contained in a vertical plane).
- Types of flexion (pure flexion; simple flexion; composite flexion - state of composite traction, state of composite flexion).
- Flat (or straight) flexion.
- Deflected flexion.
- General concepts used in the flexion theory (axis of action of the bending moment; axis of action of the transverse effort; action plane; request axis; fiber; neutral fibers; neutral surface; neutral axis; deformed; plane of deformed; moment of inertia; flexural stiffness; flexural modulus).
- Stresses in materials with linear elastic behavior in pure flexion (verification of safety in pure flexion in materials with linear elastic behavior).
- Stresses in materials with linear elastic behavior in simple flexion (verification of safety in simple flexion in materials with linear elastic behavior).
- Deformations in flexion (deformations due to the bending moment; deformations due to transverse stress).
- Central core in composite flexion.
- Bending in linear regime of mixed parts (linear elastic calculation of symmetrical reinforced concrete sections).
- Flexion in non-linear regime (flexion in non-linear elastic regime; flexion in elastic - plastic regime; flexion in fully plastic regime).
- Formation of a plastic kneecap.

Evaluation Type

Students perform evolutionary work on the material taught in class. Continuous assessment includes attendance to classes, students´ performance in carrying out the proposed exercises, delivery and evaluation of the work developed throughout the semester, all complemented with two written tests of a theoretical / practical nature.

Teaching Resources

The theoretical introduction of the material is carried out with the visualization of elements that are available to students on the moodle platform. After the theoretical introduction, exercises related to the subject follow, with the statements of these same exercises also available to students on the moodle platform.
