Resilience and Interdependencies Of Civil Infrastructures During Emergencies

Seminar | April 11 | 1-2 p.m. | Sutardja Dai Hall, 310 Banatao Auditorium

Resilience is a broad and multidisciplinary subject and measuring it is one of the most challenging tasks due to the complexity of the process. This talk analyzes fundamental concepts of “community resilience” and presents a common reference framework, including several applications of the framework to strategic facilities (e.g., hospitals and schools) and infrastructure networks (e.g., gas, water, power).

The talk will include a discussion of a hypothetical model of a hospital and school located in California, retrofitted using two different strategies. In the first, traditional performance-based earthquake evaluation tools are used to estimate the repair costs and the downtimes, the data from which is used to evaluate the resilience index of the methodology that is designed to balance the need for a hospital emergency department to be safe and damage resistant but also fully functional. In the second, an organizational model of an emergency department is applied using a discrete event simulation model that takes into account an emergency plan. The talk will present an application of this for a network of San Francisco hospitals.

The methodology can also be implemented to accommodate interdependencies at the regional level, for example using data regarding regional interdependencies to evaluate resilience within prefectures affected by the 2011 Tohoku, Japan earthquake. The talk will present a logical methodology to take into account the cascading effects during an emergency and the propagation of the probability of failure within a network.

Finally, the talk will discuss new information technologies for improving resilience and disaster management, including a new multiplatform smartphone application for field reconnaissance. The proposed application can be used in a simplified version by affected citizens to give an initial and quick damage evaluation of an area with limited resources (e.g., the number of specialists). The application was tested for the first time during the 2012 Emilia, Italy earthquake to enhance emergency response, showing the efficiency of the proposed method.

Speaker Biography:
Professor Gian Paolo Cimellaro is currently the Chair of the ASCE Committee on “Disaster Resilience of Structures, Infrastructures and Communities” in the US, and associate professor at Politecnico di Torino. In 2014-16, he was a Visiting Professor at the University of California, Berkeley. Professor Cimellaro graduated cum laude in Civil Engineering, University of Rome La Sapienza in 2001 and obtained his M.S. (2005) and Ph.D. (2008) from the University at Buffalo (SUNY). He has been a keynote lecturer in India, Chile, and Lettonia and at more than 30 invited seminars in US, Canada, and Europe. He has authored 46 journal refereed papers, 111 international conference proceedings, 12 book chapters, and 4 books. Professor Cimellaro was awarded a grant of 1.3 M € by the European Research Council for the research project “IDEAL RESCUE: Integrated Design and control of sustainable communities During emergencies”—the most prestigious prize assigned in Europe to researchers. He was also recently awarded a grant of 150000 € by the European Research Council for the project IDEAL SENSOR. He is a member of the editorial board of a number of journals, including the Journal of Earthquake Engineering and Engineering Vibration. He is also guest editor of the special Issue entitled “Resilience-Based Design of Structures and Infrastructures” in the ASCE Journal of Structural Engineering.

Professor Cimellaro’s current research interests address community disaster resilience and sustainability after natural disasters such as earthquakes; seismic risk mitigation of civil infrastructures and strategic buildings such as hospitals using advance technologies such as smart phones; monitoring and structural control of building vibrations, probabilistic methods, and earthquake engineering. In 2015, he received a seed grant award from the Siebel Energy Institute. Further details can be found in
