DESCRIPTION
The course will cover topics of scaling and modelling of structures and loads in dynamic environments. The emphasis will be on applications and case studies.
First, several concepts of structural dynamics will be introduced. Then, principles and various methods of similitude analysis and scaling will be described. Later, and for most of the course, the focus will be on applications and case studies, illustrating various aspects of modelling and different techniques of deriving scaling laws.
The last part of the course will be dedicated to seminars, presented by the students, on applications and case studies developed from results in published papers.

TOPICS
