Here you will find news relevant to the activities of the initiative including webinars, talks, consulting projects, publications, participation in conferences and meetings mostly relevant to resilience of critical infrastructure with emphasis on transport and energy assets and their intra/interdependencies, views on the UNs Sustainable Development Goals and use of digital and emerging technologies in infrastructure risk-based management
Stergios was interviewed by Sky News this morning on flood resilience of critical infrastructure, watch the video here.
The following points were communicated: The #EnvironmentAgency has improved significantly the level of understanding and the quantification of #flood #risk with the new flood risk maps. Perhaps this is an ideal time to improve the #resilience of our infrastructure assets and #networks to floods and deliver cost-effective flood-proof infrastructure by investing in alleviation and #adaptationmeasures to increased stressors exerting on our already deteriorated infrastructure
The flood risk is exacerbated due to #climatechange and the #urbanisation ie building on #floodplains susceptible to floods
Our infrastructure is exposed to stressors that deteriorate its functionality over time, and this makes the situation more difficult for infrastructure to respond successfully to new and/or aggravated natural hazard occurrences
The government has announced (5 Feb 2020) an additional investment of £2.6 billion over six years to alleviate flood risks and protect the more than 1.8 million people in the UK who live in flood-prone areas.

Today we delivered a seminar in London on Risk & Resilience of critical infrastructure. The concepts and methods for the quantification of risk and resilience are of great interest for the insurance industry, engineering consultancies, network operators and social scientists dealing with infrastructure and community resilience exposed to diverse hazards. We had a number of attendees from ARUP, Ramboll, EastWest Railway, HD Consultancy, Lynd, HDI Risk Consultancy, and OTB Engineering.
Today we had a fruitful conversation with Dr Fabien Choffat, Antonino Moltalbano and Tobias Meier. We have finalised the experimental campaign which will start in April.
The infrastructuResilience initiative is a diverse group of researchers that supports diversity and celebrates today Women and Girls’ involvement in science and Engineering!
The success of our group heavily relies on its diversity and the activities that Dimitra, Sotiria and Marianna lead in our research and consulting!
The infrastructuResilience group will be represented in the upcoming Bridges 2020 conference by Dr Sotirios Argyroudis, who will deliver an invited keynote lecture on the “Quantification of Resilience”. The conference will take place in the Ricoh Arena, Coventry, UK on 12-13 March 2020.
We won a prestigious H2020-Marie Skłodowska-Curie Actions (MSCA)-IF research grant with Dr Marianna Loli! The infrastructuresilience group is celebrating the success! Title: ReBounce-Integrated resilience assessment framework for bridges and transport networks exposed to hydraulic hazards. Partners to provide case studies: IFSTTAR, France and JBA Consulting, UK
ReBounce will deliver for the first time in the international literature a unique integrated framework for the quantification of risk and resilience of flood-critical bridges and transport networks. The research output of ReBounce will be an enabler for bridge and network resilience assessment against floods and a facilitator of decision-making in resource allocation strategies for EU bridges and transport network owners and operators. A strong case-study has been planned on the second longest bridge in Greece the 1372m-long and 45-year old Polyfytos/Servia Bridge, which suffered deterioration from multi-hazard stressors, including the 1995 earthquake, corrosion and hydraulic actions.
The 45-year old 1372m-long bridge, which is the second longest bridge of Greece, was inspected recently to provide further insights to what was visually found to be vertical displacements of the deck of the balanced-cantilever part of the structure. This second inspection followed the topographic survey of the asset that was actioned with a UAV (drone) and geodetic total station and levels of the bridge deck were identified, preliminarily assessed and recorded, whilst a 3D digital twin of the bridge with its defects is underway.
The inspection was an organised endeavor to better understand the condition of the structure and discuss with Dr Telemachos Panagiotakos/DENCO Structural Engineering these first findings. This second endeavour is a preliminary and preparatory action.
Part of this inspection was a preparatory assessment of the pathways for communicating the potential risks to the local societies and businesses and the assessment of the potential impacts. This included the communication of the engineering findings to the local authorities and stakeholders.
The resilience of the bridge, the road network and the interoperabilities with energy assets are currently under discussion.
The infrastructuresilience.com group was there and results of the ongoing H2020 projects #Briface and #TRANSRISK and other research projects #ResilienTTS were communicated to the operators and the national TV #ERT1
Ebo Emmanuel Kelechi joined the infrasrtuctuResilience group as a PhD student funded by TETFUND for 48 months. Emmanuel’s research will focus on the risk and resilience assessment of transport hubs and networks, considering their interoperabilities when exposed to multiple hazards. Emmanuel holds an MSc in Civil and Structural Engineering from Coventry University, UK and he has experience on construction, consulting in engineering and in particular for the design, construction and maintenance of infrastructure assets.
Happy to see our new paper published in the Science of The Total Environment available online here ! In this paper we have developed a novel and detailed framework for the resilience assessment of critical infrastructure exposed to a multiple-hazard environment, which is applied to a case study of a transport asset.
This is a collaborative effort between the University of Surrey: Sotirios Argyroudis, Stergios Mitoulis; University of Padova: Lorenzo Hofer, Mariano Angelo Zanini; Strathclyde University: Enrico Tubaldi, and Lehigh University: Prof Dan M Frangopol.
The framework classifies multiple hazard sequences considering their nature and impacts, and accounts for (i) the robustness of the assets to hazard actions, based on realistic fragility functions for individual and multiple hazards, and (ii) the rapidity of the recovery, based on realistic reinstatement and restoration models after individual and multiple hazard events. It provides useful insights for the resilience-based design and management of infrastructure throughout their lifetime, leading to cost savings and improved services!
