Objetivos

By the end of this course the student will acquire the competences to be able to solve problems involving the equilibrium of determinate structures in two and three dimensions; analyse the statical determinacy; determine support reactions and to represent internal forces diagrams. The student have to be able to apply the Principle of Virtual Work in determinate structures and to represent influence lines.

Resultados de aprendizagem e competências

Students must acquire basic basic skills related to isostatic structural analysis (statical determinancy, equilibrium, reactions, stresses) indispensable in a civil engineering training.

Modo de trabalho

Presencial

Pré-requisitos (conhecimentos prévios) e co-requisitos (conhecimentos simultâneos)

Knowledges of mechanics: forces, moments, equilibrium.

Programa

1 - STATICAL DETERMINACY (2,5 weeks)

diagrams. Relations between load, shear and bending moment.

4. VIRTUAL WORK PRINCIPLE (2.5 weeks)
Definition of virtual work and virtual displacement. Principle of virtual work and its application to determinate
structures.

5. INFLUENCE LINES (2 weeks)
Travelling loads. Influence lines for support reactions and internal forces in determinate structures.

Continuous assessment with a minimum mandatory attendance of 80%

Fórmula de cálculo da classificação final

Continuous Assessment (CA):

FG = Individual exercises (80%) + Moodle exercices (15%) and Laboratory Group Work (5%)

Minimum grade of the average of the 4 regular exercises: 8.0 val.


Assessment by Exam:

NF = 100% Exam

Minimum exam grade: 9.5 val.

Grades higher than 16 require an oral exam

Observações

Topics are presented previously (on printed documents and films) and the most relevant aspects are emphasized on class, followed by the resolution, by students, of practical cases.
