Subject fundamentals
The course is aimed at providing the fundamental background and the basic skills for the quantitative evaluation of seismic risk, both at regional scale and at the level of single buildings and industrial facilities. The specific elements for the evaluation are specifically treated: expected seismic hazard, vulnerability of structures and lifelines, potential economic, social and environmental consequences. Finally, the implications of seismic risk on feasibility studies and on retrofitting strategies of existing buildings will be treated.
Expected learning outcomes
Seismic risk for a single building or for a territory is a function of several factors that have to be explicitly quantified during feasibility studies and/or urban planning conception. For one, the expected seismic motion at the site needs to be evaluated considering the life span of interest and the location. In particular, the evaluation of the seismic hazard requires the characterization of potential seismic sources and the study of the propagation to the site, also accounting for ground motion modification induced by ground response and topographical effects. Then it is necessary to estimate the capacity of a given structure or a system of structures to resist to the effects of ground shakings, i.e. the structural vulnerability. Finally, it is necessary to account for the potential losses associated to failure and to the indirect consequences (e.g. pollution associated to release of toxic elements or interruption of strategic infrastructures for emergency operation. Quantification of all the above elements requires a fully multidisciplinary approach.
The course provides the basic theoretical concepts and the practical skills, which are necessary for risk analyses, both at national and local scales. Deterministic and probabilistic approaches for the evaluation of seismic hazard will be considered with reference to current national and international standards. Numerical and empirical approaches for taking into account local site conditions will also be considered. From the point of view of structural vulnerability, the methodologies for approximate and accurate evaluations will be considered for the most frequent typology of constructions. Finally, the tools for including the results of seismic analyses into urban planning and into mitigation plans will be considered.

Delivery modes
Practical examples will be presented in the classroom to make the students familiar with the topics of the course. Some practical examples will be devoted to the use of computer software. The students are required to prepare as an homework a reported on seismic risk with quantitative evaluation for a given regional context.

Assessment and grading criteria
The final assessment will be based on an oral examination in which the students are required to demonstrate the knowledge of the theoretical aspects and to discuss the homework that will be assigned during the course. The grade is dependent in equal parts on these assessments.
