Mechanics

In the classes, both expository and interrogative methods are used. During the explanation of the theoretical subjects, the respective physical interpretation and technological details are used as complementary approach; students proceed to solving exercises, individually or in groups.
In some classes, tutorial type, individual learning skills and teamwork are explored, by clarifying theoretical and practical questions and monitoring the various works.
Assessment: Final Exam, written and conducted individually, is quoted to 20 values, and the approval requires that the obtained grade is greater than or equal to 10. It is planned to carry out written or oral examination to students who require special exams.

Objectives: learn the theoretical bases, the practical and technological knowledge, to apply to the design and construction of new structures and of reinforcement for the existing ones.
Generic skills: apprehension capacity, analysis and synthesis; problem­solving capacity and application of knowledge and adapt to new situations; ability to carry out independent and group work and autonomy in learning; ability to predict and produce judgments and to discuss technology issues; development of critical sense.
Specific skills: know the theoretical, practical and technological bases, relating to the design and construction of structures in several materials; know the internal stresses in structural elements, depending on the actions and resulting internal forces, simple and combined; acquire knowledge to understand the design criteria and to prevent, recognize, diagnose and intervene in structural pathologies.
