Sustainable Development Goals

Learning Goals

Apprehension of basic knowledge about mechanics and resistance of materials, so that students can better reconcile structural systems with architectural design.

Contents

1. Mass and weight. Acceleration of gravity. Units of S.I.
2. Particle equilibrium. Notion of force. Traction and compression. Diagram of axial forces. Notion of tension and extension. Law of Hooke. Linear and non-linear behavior. Elastic and plastic behavior. Behavior fragile and ductile.
3. Cables and arcs. Stability. Efforts. Analogy between cables and arcs. Stability of domes and vaults.
4. Isostatic and hyperstatic structures: Degrees of freedom and connections to the outside. Balance conditions in space and plane. Notion of moment of a force. Types of support and reactions generated.
5. Isostatic trusses. Method of the nodes and method of the sections. Identification of the type of stress to which each bar is subject: traction or compression.
6. Efforts in linear rigid bodies: Transverse stress, Bending and torsor moments. Determination of the reactions in the supports. Sign Convention. Diagrams of stresses (transverse stress and bending moment)

Teaching Methods

The course is organized in theoretical-practical classes, which are organized in oral presentations, written exercises and discussion.

Assessment

The classification in this curricular unit may result from one of the following evaluation schemes: continuous evaluation or final examination.
Continuous frequency evaluation: FinalScore = (0.8xF) + (0.1xAM) + (0.1xA)
Evaluation by exam: FinalScore = (0.8xEN) + (0.1xAM) + (0.1xA)
Evaluation by appeal time exam, special season exam and extraordinary season exam: Final score = (1.0xE)

In which:
FinalScore - cannot be less than 10 points.
F – 2 frequencies whose arithmetic mean cannot be less than 10 points and the minimum grade in each frequency cannot be less than 7.5 points.
EN – exam whose minimum score is 10 points.
E – exam whose minimum score is 10 points.
AM - monitoring of the subject throughout the semester.
A - assiduity to classes.

Attendance in classes is mandatory (75% of classes). Anyone who exceeds the number of absences will only be able to take the appeal exam.
