ReBounce (H2020-MSCA-IF-2019): Integrated resilience assessment framework for bridges and transport networks exposed to hydraulic hazards
ReBounce will deliver for the first time in the international literature a unique integrated framework for the quantification of risk and resilience of flood-critical bridges and transport networks. The research output of ReBounce will be an enabler for bridge and network resilience assessment against floods and a facilitator of decision-making in resource allocation strategies for EU bridges and transport network owners and operators. A strong case-study has been planned on the second longest bridge in Greece the 1372m-long and 45-year old Polyfytos/Servia Bridge, which suffered deterioration from multi-hazard stressors, including the 1995 earthquake, corrosion and hydraulic actions.
The ultimate goal of the project is to deliver a robust framework for Quantitative Risk and Resilience Analysis of bridges and transport networks exposed to flood-induced stressors. Core to this venture is the development of new, adaptive fragility and recovery functions for delivering original resilience models for different bridge typologies met in the EU and evaluating their impact on the operability of transport networks. ReBounce has the following bottom-up measurable objectives:
Obj.1 Define realistic and sufficient flood intensity measures for bridge typologies found in Europe.
Obj.2 Deliver novel adaptive fragility models for representative typologies of bridges in Europe, incorporating temporal variations with respect to the cumulative effects of scour and debris built-up (SDF history), material deterioration with age and improvements due to mitigation measures.
Obj.3 Develop original multi-parameter restoration functions capable of modelling the effect of restoration tasks on the functionality of bridges, damaged due to SDF, over time.
Obj.4 Apply the proposed framework for assessing the resilience of critical EU road network.
