Bridges

Objectives

1. Identify the relevant issues related to the design and construction of bridges and viaducts, with particular emphasis to the prestressed reinforced concrete ones, which are the most used in Portugal.

2. Identify the structural function of constituent parts of bridges and viaducts.

3. Know the main actions.

4. Provide knowledge in the choice and use of analytical methods for the determination of the effects of structural actions.

5. Provide knowledge on the dimensioning and safety checks of the different structural parts.

6. Provide knowledge in the choice of solutions for bridges and viaducts of medium spans.

7. Associate the structural conception to the construction methods.
