LEARNING OUTCOMES

The course provides the fundamentals and the operative techniques of wind engineering with special regard for wind actions and effects on structures.

AIMS AND LEARNING OUTCOMES

Knowledge of the fundamentals of Structural dynamics is required.

TEACHING METHODS

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.
