TC219 Seminar Series on Resilience Evaluation in Geotechnical Engineering
Multi-hazard resilience assessment of critical infrastructure
Dr Sotirios Argyroudis, CEng, MICE, FHEA
Associate Professor (Reader) in Infrastructure Engineering
Abstract
Our critical infrastructure is exposed to multiple hazards, some of which are exacerbated by the effects of climate change. Their failure can lead to significant cascading events and disruptions across communities. Therefore, assessing the resilience of infrastructure assets to extreme events is paramount for maintaining their functionality. Infrastructure operators need practical tools and metrics to assess vulnerabilities and resilience, enabling them to rapidly restore services and minimize disruptions. This lecture will present examples of the impacts of natural hazards on critical transport infrastructure and introduce a framework for multihazard resilience assessment, including fragility and restoration models. Methods for developing fragility functions will be presented and challenges in modeling combined hazards will be discussed. Examples of fragility analysis for different hazards (e.g., floods, scour, seismic actions) based on numerical modeling will be presented for geotechnical assets, such as bridge foundations, abutments, embankments, and tunnels. Additionally, restoration models for flood-affected bridges will be presented, along with resilience assessment examples
About the speaker
Dr Sotirios Argyroudis is Associate Professor at Brunel University London, UK, and cofounder of the www.metaInfrastructure.org initiative. With over 22 years of experience in disaster risk and resilience assessment of critical infrastructure (including bridges, tunnels, embankments, slopes, retaining walls, highways/railways, ports, and airports) exposed to multiple hazards (e.g. earthquakes, floods, wildfires) and climate change effects he is leading expert in his field. He holds degrees in Civil Engineering and Geology and a PhD in Geotechnical Earthquake Engineering. He has published over 150 scientific articles in journals, conferences, and books with over 3,700 citations (h-index 30, Google Scholar). He has won and participated in several research projects and is currently the deputy scientific coordinator of the Horizon/UKRI ReCharged project. He is in the top 2% of most highly cited scientists for 2021, 2022, and 2023, according to the Elsevier/Stanford list. Fellow of the Higher Education Academy, UK, and member of the Institution of Civil Engineers (UK), CEng, MICE. Deputy Editor of ICE Proceedings Bridge Engineering (Emerald Publishing). Vice-chair of IABSE TG1.8 “Design Requirements for Infrastructure Resilience and member of the ISSMGE TC202 on Transportation Geotechnics. In 2017 he was awarded the European Commission’s Marie-Sklodowska-Curie postdoctoral fellowship.
