# 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 staticaly analysis of structures. In the theoretical-practical classes, exercises will be applied to current structures. At the evaluation level, two tests ( of 50% each) are performed in normal times with a minimum score of 8.0 / 20.0 at each. In Season of Appeal (and the Special Season), all components of evaluation of the Normal Season are fully recoverable, ie, examination of Appeal season (and the Special Season) is necessarily performed to 100%. Students who achieve a grade (Regular Season / Appeal / Special) of at least 18.5 must undergo the oral examination to qualify to obtain a final grade of more than 18 values (if they do not, the final grade is 18).
