The dynamic response of the subsoil has a strong influence on seismic risk. Indeed it affects the seismic hazard and the soil-foundation-structure interaction. The course, after the introduction of the basics of seismology and soil dynamics, deals with geotechnical issues of engineering structures under seismic loads.

Understanding of the seismic response of soil deposits and its influence on the seismic hazard for the construction site. Ability to build simplified models for the prediction of the seismic response of site, the analysis of seismic hazards and the analysis of soil-structure interaction.

Basics of Mechanics and of Soil Mechanics

•Fundamentals of Engineering Seismology (9h) •Seismic wave propagation in soils (9h) •Behaviour of soils under cyclic and dynamic loads (3h) •Experimental Soil Dynamics (in situ and laboratory testing) (8h) •Seismic site response (12h) •Liquefaction (8h) •Retaining walls (9h) •Soil-structure interaction (6h)

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 softwares for the numerical simulation of geotechnical earthquake engineering problems.

Exam: Compulsory oral exam; Individual essay;

... The exam is composed by an homework in 3 parts and an oral exam. The homework is intended to provide the practical skills necessary for the quantitative assessment of seismic hazard at a site, including the evaluation of the stability of a retaining structure, which will consider also the evaluation of its performances. The oral exam is intended to evaluate the comprehension of the background theory and to assess the full understanding of the topics covered by the homework. Frading will be based in equal parts on these assessments
