COURSE - Elements of dynamic identification of structures: general issues and applications

The course deals with the peculiar aspects of the structural identification of existing buildings, taking into account both the notional issues and the related practical implications. Attention will be focused on methods encompassing dynamic data. The problems arising in this context have an inverse nature, compared to the classic direct problems of the dynamics of structures, and present some specific ‘pathologies’. These may be related to the non-uniqueness of the solution or the lack of continuous dependence of the solution on the input data. During the course we will address some of these aspects, with reference to both simple structural models and mechanical systems of greater complexity and interest in engineering applications. The aim of the course is twofold: to consolidate the basic knowledge on structural identification issues, and to stimulate interest towards research topics belonging to this area.
