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
A new paper on “Multiple hazard fragility analysis for granular highway embankments: moisture ingress and scour” has been published in Transportation Geotechnics. This is the result of a collaborative effort between Greg McKeena (ByrneLooby Partners Ltd), Dr Mike G Winter (Winter Associates), Dr Sotirios Argyroudis and Dr Stergios Mitoulis.
The study provides a basis for the prediction of embankment deformation, and hence of damage, due to moisture ingress and scour, which can be aggravated by climate change. This can be used for the assessment of existing assets, and the design of new ones in the pursuit of more resilient transport networks, as well as for other assets such as levees, dams and other similar earthworks, with some limitations. A journal pre-proof is available here
our second paper this year in the Science of the Total Engvironment is discussing how resilience of transport infrastructure can be enhanced by deploying digital technologies:
Monitoring of transport infrastructure exposed to multiple hazards: a roadmap for building resilience
by Dimitra V Achillopoulou, Stergios A Mitoulis, Sotirios A Argyroudis and Ying Wang
Our new paper published in the ASCE Journal of Structural Engineering is on the fragility of bridge elastomeric bearings, on the basis of a novel damage index, and the influence of steel reinforcement plates on their performance.
The paper is co-authored with Dr Kostas Kalfas from Southern Methodist University and Prof Dimitris Konstantinidis, Berkeley University

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/
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/
