Bridges 2020 28th Annual Conference and Exhibition Ricoh Arena, Coventry, UK 12th March 2020

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/
