The course will address the topic of seismic risk assessment, emergency management and mitigation of the built environment. After an introduction to natural disasters and risk elements (hazard, exposure and vulnerability), we will present the concept of resilience and its interdisciplinary applications. Then, starting from the basics of seismic hazard, seismic action and dynamic response of structural systems, we will discuss the effects on environment and structures, focusing on the concept of vulnerability of buildings (masonry and reinforced concrete ones). The next step will be an overview of different possible seismic risk reduction policies in the three phases of risk management (pre-event, emergency state and post-event). Finally, the course will focus on the damage survey activities run by the Civil Protection in the post-earthquake emergency phase to evaluate the structures’ usability. In particular, firstly we will describe the different forms currently available for damage, emergency provisions and practicability assessment of ordinary buildings and churches; secondly, we will see some practical examples of post-earthquake damage survey applied to some case-studies hit by the last Italian earthquakes in order to evaluate the damage and vulnerability indexes.
At the end of the course, students should be able to:
Front lessons and practical applications:
1. Risk on the built environment
Introduction to natural disasters and risk elements (hazard, exposure and vulnerability); Resilience concept and its interdisciplinary applications
2. Seismic Hazard (recall to the basics concepts)
3. Exposure information
Introduction to the people, property, other assets or systems exposed to seismic hazards
4. Dynamic response of structural systems and seismic action (recall to the basics concepts)
Introduction to the basic concepts of structural dynamics by means of an elementary mathematical model: the SDOF system
5. Vulnerability to earthquakes, part I: seismic response of reinforced concrete (RC) structures
6. Vulnerability to earthquakes, part I: seismic response of masonry structures
7. Vulnerability to earthquakes, part II: fragility curves
Analysis of the different approaches for the derivation of fragility curves: empirical, expert elicitation, numerical and hybrid methods; critical aspects in the derivation; treatment of uncertainties; practical example on the definition of numerical fragility curves
8. Seismic risk reduction policies in the three phases of risk management: pre-event, emergency state and post-event
Presentation of the three phases of risk management and overview on the different possible risk reduction policies: 1) pre-event (Mitigation efforts and Preparedness – education, emergency management planning); 2) response (Emergency state); 3) post-event (Recovery)
9. Post-earthquake damage survey

All class schedules are posted on the EasyAcademy portal.
Students with learning disorders will be allowed to use specific modalities and supports that will be determined on a case-by-case basis in agreement with the delegate of the Engineering courses in the Committee for the Inclusion of Students with Disabilities.
The oral exam consists in the discussion of a report/presentation carried out by the student, related to the practical exercises developed during the course with the aim to evaluate: if the student achieved a proper level of knowledge; his/her skill to describe the topics clearly and with a proper terminology.
All course information is given in the classroom, through Aulaweb or on Teams.
For further information, the student can contact the teacher by email.
