Assesssment methods and criteria:

Classification Type: Quantitativa (0-20)

Evaluation Methodology:
In the theoretical classes will be presented, deduced and demonstrated the fundamentals and the calculation methodologies that allow the analysis of structures. In the theoretical-practical classes, exercises will be applied to current structures. In the evaluation will be realized three tests (30% each) and two works (5% each) with the objective of assessing theoretical and theoretical-practical knowledge. In this way, the student can, during the semester, evaluate their performance and change strategies if necessary. Resource and special seasons: final exam that covers the various topics of the curricular unit. Students who obtain a classification higher than 17 values are subject to oral test to be able to obtain a final classification higher than 17 values.
