Our latest scientific paper on prestressed bridge deflections, has a lot of valuable information for a recent consultancy on the lake Polyfytos Bridge: http://www.infrastructuresilience.com/lake-polyfytos-bridge
Title: Control of long-term deflections of RC beams using reinforcements and low-shrinkage concrete authored by H. Sousa, S. Mitoulis, K. Psarras, I. Tegos. The paper explains how bridge vertical deflections can be alleviated by making use of low shrinkage concrete. The paper can be found here.
The Turkish Association for Bridge and Structural Engineers, the Turkish chapter for IABSE and the organisers of the 4th Istanbul Bridge Conference (iBridge-2020) have invited Dr Stergios A Mitoulis to the scientific committee of the Conference to be held on 16-17 November 2020 in Istanbul: https://ibridgeconference.org/
12:30 – 14:30 GMT, 24th April 2020
Agenda : In this webinar you will learn about resilience-based decision making in infrastructure management and will be split into 2 parts. The first part of the webinar will look at vulnerability and risk-based decision making (1hr Sotirios Argyroudis) and will cover areas including fragility & vulnerability assessment, direct losses, quantification of risk for different hazards and infrastructure, The second part will look at resilience-based assessment and management (1hr, Stergios Mitoulis) and will cover areas including quantification of resilience, resilience indices, including robustness of structures, sequences of hazards, restoration strategies, and direct/indirect costs for critical infrastructure.
Dr Sotirios Argyroudis delivered a keynote lecture on the “Quantification of Resilience” in the ‘Bridges2020’ conference, which took place in the Ricoh Arena, Coventry UK, on 12 & 13 March 2020.
The exposure of transport infrastructure to natural hazards such as floods or ground movements was proven to have severe consequences on economies and societies, which are expected to be exacerbated due to climate change. Thus, pinpointing the vulnerabilities and quantifying the resilience of infrastructure exposed to multiple hazards is of paramount importance for stakeholders, network operators and owners, toward more efficient allocation of their resources and rapid decision-making.
In this lecture, a resilience assessment framework for infrastructure assets exposed to individual and multiple natural hazard events is introduced. This framework considers the factors that reflect redundancy and resourcefulness in infrastructure, i.e. (i) the robustness to hazard actions, based on realistic fragility functions, and (ii) the rapidity of the recovery, based on realistic restoration and reinstatement functions. Examples were also presented including estimation of resilience indexes and indirect losses due to bridge closures. This lecture was part of the H2020-MSCA-IF TRANSRISK research project at University of Surrey: http://www.infrastructuresilience.com/transrisk/
Our group celebrates International Women’s Day!
We embrace equality and balance for progress!
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!
