Risk & Resilience of Critical Infrastructure Exposed to Diverse Hazards

17th February 2020, London

The exposure of critical infrastructure to natural hazards is proven to have severe consequences on world economies and societies. Therefore, risk and resilience assessment of infrastructure assets and networks to extreme events and sequences of diverse hazards is of paramount importance for maintaining their functionality and continuous operation even after severe natural and human-induced hazards. In this context, engineers, consultants, owners and operators would be benefited in the design, assessment and decision-making process from quantifications of risk and resilience. This quantification should account for the sequence of hazards, the type and extent of damage and impact on asset or network functionality, the latter expressed by robustness, and the importance of the asset, the available resources and priorities, including the rapidity and resourcefulness.

This course will provide a systematic introduction to the concept of risk and resilience assessment of critical infrastructure. The main emphasis of this course is on the understanding of the fundamental principles to help the learner to confidently build up their knowledge in this specialist subject. Examples and practical applications will be presented to illustrate the main components of risk and resilience, i.e. hazard actions, typology of infrastructure (e.g. highways, railways, ports, water, energy system) damage modes, fragility/vulnerability analysis, loss assessment (direct/indirect), restoration, mitigation measures and decision-making for networks.

Lecture 1 Introduction to risk & resilience of critical infrastructure

This lecture will classify the natural hazards and disasters and will describe their consequences on infrastructure (e.g. bridges, tunnels, dams, pipelines) and networks, including examples from past events in the UK and worldwide. Design codes and existing standards including assessment and inspection options will be presented. Hazard actions (floods, earthquakes, ground movements and other accidental actions), failure modes and design aspects of key structural components will be outlined. The definitions for hazard, exposure, vulnerability, risk, losses (direct/indirect), resilience will be given, along with representative examples. The general framework for the risk and resilience-based design and management will be introduced at the component level (e.g. a bridge) and at the network level (e.g. motorway).

 

Lecture 2 Vulnerability assessment of infrastructure assets

The characteristics that define the typology of the assets will be presented with relevant examples, including the description of damage states. The concepts of fragility analysis for single and multiple hazards will be presented, including methods and examples based on empirical, numerical, expert elicitation and experimental approaches. The effect of environmental deterioration and mitigation on the fragility of the infrastructure assets will be highlighted. The concept of vulnerability curves, which are based on repair ratios and correlation of damage to loss of functionality, will be described.

Assessment unit 1: Worked example on vulnerability and/or multiple-choice questions

 

Lecture 3 Risk analysis

In this lecture, the methodology for risk analysis for portfolios of assets and networks to given hazards will be provided, and examples will be presented. Loss assessments will be in terms of direct (physical) and indirect (traffic or business interruption in case of transport networks) losses.

 

Lecture 4 Resilience analysis and mitigation measures

The methodology for the quantification of resilience will be presented, including the robustness of the structure, the rapidity of restoration and relevant resilience indices. Examples will be also provided and discussed. Available restoration models for single and multiple hazards accounting for costs and rapidity of the restoration will be presented, as a tool for efficient mitigation strategies. The scope of the latter is to prioritise the exposed assets and facilitate the decision making for restoration/retrofitting on network scale.

About the Lecturers

Dr Stergios Mitoulis is the leader of the infrastructuResilience initiative. Over the last ten years he has supervised and co-supervised seven doctoral and postdoctoral students. He has published extensively with a publication record exceeding 100 papers in leading scientific journals and international conferences. His expertise is the resilience-based design and assessment of infrastructure assets and in particular bridges subjected to extreme natural hazards, dynamic loads, hydraulic hazards, creep, shrinkage and thermal effects. He is a member of the BSI B/525/10 CEN/TC250/HG-Bridges, the BSI Mirror Group of Eurocodes and UK delegate of the BSI (CEN/TC250/SC8 Work Group 6, Bridges) for the design and retrofit of bridges, the BSI committee B/525/8 and B/538/5 and the Workgroup 11 of the EAEE. He has worked extensively on the modelling, resilient design and assessment of infrastructure assets with emphasis on bridges, foundations, abutments and backfills and use of waste materials in infrastructure. SM was and still is the Supervisor and co-supervisor of European projects, the last commenced in 2017, while has been the Principal Investigator (PI) of two KTP (Innovate UK) projects and a proof-of-concept project with Network Rail-UK on the monitoring of environmental hazards on infrastructure. SM has worked as Co-PI and researcher for another 11 research projects, relevant to bridge and networks resilience. He has editorial and reviewing responsibilities in reputed journals (more than 30). SM has served as evaluator for EU proposals and research grants within the UK (EPSRC), Canada and Latvia. He is an active consultant for industries in the UK and Belgium. He delivers seminars at consultancies and also participates in CPD activities as an official lecturer of the Institution of Civil Engineers in the UK. He has an extensive presence in the news of leading news agencies, including the BBC.

 

Dr Sotiris Argyroudis is Research Fellow, at the Dpt of Civil & Environmental Eng, University of Surrey, and Senior Teaching/Research Staff at the Dpt of Civil Eng, Aristotle University. Dr Argyroudis is civil engineer and geologist. He has 17 years of research experience in the field of geotechnical and infrastructure engineering, with focus on the risk and resilience analysis of infrastructure due to geo-hazards (earthquake, flood/scour, landslides, tsunamis). He has more than 100 reports and publications in scientific journals, conference proceedings and book chapters and participated in 15 national and European research projects. He acted as a reviewer for more than 20 scientific journals and for research proposals. In 2017 he was awarded a H2020 Marie Skłodowska-Curie Individual Fellowship. He is a member of the Working Group 13 of the EAEE on assessment, design and resilience of industrial facilities and vice-chair of the IABSE Task Group on design requirements for infrastructure resilience.
