Contents Introduction to Soil Mechanics and basic concepts of Rock Mechanics.
Principles of Earthquake Geotechnical Engineering
Design criteria and stability verifications aimed at the safety of geotechnical works/systems.
Reference texts 1. Lectures notes.
2. "Geotechnical Earthquake Engineering" di Kramer, 1996, Prentice Hall.
3. "Risposta sismica locale", di Lanzo, Silvestri, 1999, Hevelius Edizioni.
4. "Introduction to Rock Mechanics" di Goodman, 1989, Wiley.
Educational objectives The purpouse of this course is to introduce the Student to the concepts, theories and procedures of Geotechnical Engineering finalized to the safety and protection of geotechnical systems in static and seismic conditions.
Prerequisites In order to fully understand the topics of this Course, Students have to know the basic concepts of Geotechnics, dealt with during the basic courses of a 3-years Degree in Civil Engineering.
Teaching methods Face to face (4 hours per week) and practical training in class.
Possible field trips.
Other information Attending the lessons is optional but strongly suggested.
Learning verification modality Oral exam.
The exam will take not more than 45 min. The exam is aimed at verifying: a) the level of knowledge; b) the ability of the Student to discuss possible design solutions aimed at verifying the safety of geotechnical works and systems in seismic areas.
Extended program Introduction to Soil Mechanics and basic concepts of Rock Mechanics.
Dynamic soil properties from
in situ investigations and laboratory testing. Seismic actions.
Design criteria and stability verifications for excavation cuts, natural rock/soil slopes and other geotechnical works/systems. Pseudostatic and Newmark-type pseudodynamic approaches.
Numerical examples and case hystories.

Notes from the lessons.
Educational objectives The main objective of the "seismology and seismic risk" course is to provide students the basic knowledge on the earthquake physics and the seismic risk assessment.
The main knowledge gained will be:
- basic elements on earthquake physics and parameters useful to describe the earthquakes;
- basic elements on risk, and in particular on seismic risk.
The main ability gained will be:
- critical thinking ability on seismic processes and their hazard;
- comprehensive view of the seismic risk issue;
- use of technical scientific language.
Prerequisites In order to understand the topics described within the course, it is important to have the basics of physics and mathematics.
Teaching methods Face to face, pratical training.
