Analysis of Structures

– Knowledge of applied mechanics and strength of materials (forces and moments, principles of equilibrium of a body, calculation of reactions, internal efforts, deformations.

– Knowledge of mathematics, including mathematical integration.

– User friendly computer skills

The expository and inquisitive method is used (taught in Portuguese). Students are encouraged to develop a critical spirit and to discuss the topics covered. Exercises are done in groups and individually. Students are encouraged to participate actively in class. The clarification of doubts will also be important for the development of the desired competences.

Students may, eventually, carry out practical research, either individually or in groups, to develop/improve their technical-scientific interpretation of structural problems.

Goals:

Develop the ability to analyse structures, particularly in the determination of forces and deformations. Acquire knowledge of the behaviour of statically indeterminate structures in the linear regime.

Generic competences:

To improve communication, research and self-learning skills; to develop judgement and decision-making skills.

Specific competences:

Acquire knowledge and ability to understand the behaviour of building structures, particularly in the analysis of the response of the structure to applied actions.
