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 “Cost-based resilience assessment of bridges subjected to earthquakes” has been published in the International Journal of Disaster Resilience in the Built Environment, by Sotirios Argyroudis, Giorgos Nasiopoulos, Nikolaos Mantadakis and Stergios Mitoulis.
Transport infrastructure resilience is of paramount importance for societies, therefore its quantification is urgently needed. A resilience assessment framework based on well-informed resilience indices is presented and applied for assessing the resilience of representative bridges exposed to earthquakes.
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

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.
