Students acquire mastery in the calculation of the structures to wind actions and sensitivity to recognize the structures sensitive to aeroelastic instability phenomena.
The module provides the fundamentals for the analysis of steel structures. The linear elastic and non-linear behavior of steel beams is analyzed as well as their stability, the bolted and welded connections, the wind and seismic loads.
Knowledge of the fundamentals of Structural dynamics is required.
The course consists of lectures during which theoretical, experimental, and numerical applications are illustrated, with examples related to real structures. The students develop, in small working groups, an assisted project report related to a real structure.

At the beginning of the second semester, according to Faculty timetable.
The examination includes an oral discussion based on two/three theoretical questions related to topics dealt with in the course. During the examination the students also discuss the project report developed in small groups.
Oral examination
