Stergios is giving an invited lecture on “Risk and Resilience of Bridges and Networks” at ETH Zurich-Institute of Structural Engineering on Monday 21st of October. Abstract: The exposure of bridges and transportation networks to natural hazards is proven to have severe consequences on world economies and societies. Therefore, risk and resilience assessment of these assets to extreme events and sequences of diverse hazards is of paramount importance for maintaining their functionality and continuous operation even after severe natural and human-induced hazards. In this context, engineers, consultants, owners and operators would be benefited in the design, assessment and decision-making process from quantifications of risk and resilience. This quantification should account for the sequence of hazards, the type and extent of damage and impact in bridge or network functionality, the latter expressed by robustness, and the importance of the asset, the available resources and priorities, including the rapidity and resourcefulness. This lecture will provide a systematic introduction to the concept of risk and resilience assessment of bridges and transportation networks. Examples and practical applications will be presented to illustrate the main components of risk and resilience, i.e. hazard actions, typology of bridges, damage modes, fragility/vulnerability analysis, loss assessment (direct/indirect), restoration, mitigation measures and decision-making for networks.

Stergios Mitoulis and Dimitra Achillopooulou represent our group at the “Lloyd’s Register Foundation International Conference 2019” in London, 9-10 October.

Interesting discussions  and insights toward engineering a safer and more resilient world!

 

We participated in the SECED2019 conference in Greenwich, London, 9-10 September 2019, presenting a paper on the “Fragility of bridges exposed to multiple hazards and impact on transport network resilience” (by Yuan V,  Argyroudis S,  Tubaldi E, Pregnolato M, Mitoulis S) and organised a session on “Fragility, vulnerability & infrastructure resilience” with inspiring discussions toward “a resilient world”.

Our group participated in the 2019 IABSE Congress in New York City, 4-6 September. The theme of the congress was the “Evolving Metropolis”, where we presented our work on “Risk and resilience of bridgeworks exposed to hydraulic hazards”,  by S Mitoulis, S Argyroudis and R Lamb.

Dr Dimitra Achillopoulou was shortlisted for the young engineers award and presented her project on “Novel assessment of bridge retrofitting measures through Interface Efficiency Indices using a Guided Wave-based monitoring method”.

Our paper on “Fragility of transport assets exposed to multiple hazards: State-of-the-art review toward infrastructural resilience” in Reliability Engineering & System Safety is now available online!

This is a collaborative work between infrasrtuctuResilience group and Mike G Winter (Winter Associates, formerly TRL) & Amir M Kaynia (NGI), in the framework of TRANSRISK H2020-MSCA-IF project.

It was an honour that Dr Stergios Mitoulis has been invited to join the editorial panel of the Journal of Bridge Engineering, at Institution of Civil Engineers (ICE), UK.

This is a prestigious journal of the ICE, attracts both academic papers and real bridge applications. More information for the Journal can be found here: www.icevirtuallibrary.com/toc/jbren/current  

Our group participated in the event organised by the EPICentre at University College London (UCL) on 2-3 July 2019: “Recent advances and perspectives in multi-hazard risk and resilience”

Dr S Mitoulis presented our recent developments and ideas on “Resilience of transport infrastructure exposed to multiple hazards with applications on bridges”

We participated to ICONHIC2019: 2nd International Conference on Natural Hazards & Infrastructure, 23-26 June in Chania, Greece.

Glad to present our recent work on resilience assessment of infrastructure, and to meet with friends and colleagues.

our papers:

“Resilience of critical infrastructure for multiple hazards: Case study on a highway bridge”, by Argyroudis S, Hofer L, Zanini MA, Mitoulis S

&

“Resilience of bridges subjected to earthquakes: A case study on a portfolio of road bridges”, by Nasiopoulos G, Mantadakis N, Pitilakis D, Argyroudis SA, Mitoulis SA

We are happy to announce a specialised seminar on the Fragility assessment for retrofit prioritisation of bridges and impact on the road network, which will be delivered on 12 July 2019 by Dr Sotiria Stefanidou, Postdoctoral Researcher & visiting lecturer of the International Hellenic University.

The seminar will take place on Friday 12 July 2019, 12:00-13:00, at the University of Surrey, room  39 BB 02. Any enquiries, please email k.oliver@surrey.ac.uk , www.surrey.ac.uk/cee

In the framework of DYMOBRIS H2020-SERA-TA project, we have successfully performed the experiments at the Europroteas facility, Greece on the 6th of June.  The scour effects in the dynamic response of the Soil-Foundation-Structure systems were monitored under variable vibration frequencies. The results of this project will provide a unique benchmark for informing both the design and assessment of bridges and other marine structures subjected to a sequence of scour and earthquake effects.
