Learning outcomes of the course unit
Knowledge and understanding:
At the end of this course the student should know elementary analysis methods to evaluate stress and strain states of the structures. Moreover, he should gain understanding of the fundamental principles of the design methods and evaluation of structural reliability, as well as instruments and techniques to draft the structural design.
Applying knowledge and understanding:
The student should be able to compute actions on constructions and resultants stress and strain fields in the structure, to design reinforced concrete and steel structural elements, including foundations and supports, on the basis of design codes. Finally, the student should be able to draft design results with relative details.
By the end of the course, the student should be able to evaluate, with critical mind, the good choice for the structural element design and its feasibleness.
The student should be able to clearly present the results of the design activity by means of tables, charts and drawings.
Knowledge of basic concepts on differential equations, stress analysis, strength of material and theory of elastic beams.

Slides will be used to convey the most important messages of the theory lectures. Practical lectures will perform by design examples on reinforced concrete and steel elements, as well as drawing construction details, under the guide of tutors.
Assessment methods and criteria
The examination is based on a written test concerning stress analysis of frame structure and an oral exam concerning design models and codes. The examination is weighted as follows: 40% written test (appropriate approach of analysis, correctness and clarity in presenting the results); 60% oral exam (theory questions, application of theory to design problems and presentation ability).
Lecture attendance is highly recommended.
