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.

loads, as a result of the dead and the horizontal loads, i.e. wind and seismic loads, acting on the structure. It is only very recently that tensile stresses in bearings were studied, as it was observed that local and global tensile stresses might be developed in bearings under seismic excitations. Most importantly, tension within the elastomer might cause local cracks or, in extreme cases, rupture of the elastomer, which might lead to the loss of support of isolated structures. Yet only a few studies exist in the international literature with regard to response of these devices under combined axial and shear loads. The aforementioned gap in the knowledge and the identified rupture of the elastomer of bearings under tensile loads during recent earthquakes comprised the motivation for this research. In this context, this paper examines the response of steel-laminated elastomeric bearings under cyclic shear and variable axial loads and aims to better understand their behaviour with emphasis
placed on the tensile stresses within the elastomer, their stiffness and dissipation capacity. Extensive numerical research was conducted with ABAQUS and the Ogden hyperelastic model was used for modelling the
elastomeric material. The analyses showed that steel-laminated elastomeric bearings exhibit local tensile
stresses, which alter significantly their stiffness and damping ratio. Most importantly, significant tensile stresses
within the elastomer were observed locally, even when the bearings were subjected to a combination of shearing
In this paper, the dynamic behaviour and seismic response of a benchmark three-span bridge are analysed by using an advanced HDNR bearing model recently developed and capable of accounting for the coupled horizontal and vertical responses, as well as for significant features of the hysteretic shear response of these isolation devices. The results of the analyses shed light on the importance of the bearing vertical stiffness and how it modifies the seismic performance of isolated bridges. Successively, the seismic response estimates obtained by using simplified bearing models, whose use is well established and also suggested by design codes, are compared against the corresponding estimates obtained by using the advanced bearing model, to evaluate their accuracy for the current design practice.
critical transportation infrastructure subjected to earthquake excitations with emphasis placed on
geotechnical effects. Available approaches to fragility analysis are summarized, along with the
main parameters and limitations. Additionally, definitions of damage are synthesized for the
individual transportation assets and subsequently the definition of system of assets (SoA) is
introduced. Numerical fragility curves are developed for a representative SoA subjected to
seismic excitations. The paper concludes with the gaps in the area of fragility analysis and the
needs for future development.
The exposure of critical infrastructure to natural hazards was proven to have severe consequences on world economies and societies. Therefore, resilience assessment of an infrastructure asset to extreme events and sequences of diverse hazards is of paramount importance for maintaining their functionality. However, the resilience assessment commonly assumes single hazards and one restoration strategy. In addition, owners and operators have different approaches for restoring their assets, depending on different factors, such as the available resources and their priorities, the importance of the asset and the level of damage. Yet, currently no integrated framework that accounts for the different strategies of restoration, and hence quantification of resilience in that respect exists.
This paper proposes an integrated framework for the quantitative risk and resilience assessment of critical infrastructure,
subjected to multiple natural hazards, considering the factors that reflect redundancy and resourcefulness in infrastructure,
i.e., (i) the robustness to hazard actions, based on realistic fragility curves, and (ii) the rapidity of the recovery after the
occurrence of damages, based on realistic restoration functions. Lastly, the paper includes an application of the proposed
framework for a typical highway bridge for realistic multiple hazard scenarios and restoration strategies using a wellinformed
services and transportation of goods and people, under normal and emergency circumstances.
Bridges act as bottlenecks within road and rail networks, since bridges are crunch points along
the network system. Their failures due to multiple natural hazards (e.g. floods, earthquakes,
tsunami or ground movements) may cause disproportionate losses, which are expected to be
exacerbated due to climate change. Thus, pinpointing the vulnerabilities and quantifying bridge
resilience within transportation networks is of paramount importance in the context of natural
hazards. However, reliable quantification of risk and resilience of bridges is not yet available, as
engineering judgment dominates quantitative assessments. This paper describes an integrated
framework for the development of numerical fragility functions and the resilience assessment of
bridges subjected to multiple hazards. The framework is applied to obtain the fragility of a
representative bridge exposed to flood-induced scour followed by an earthquake. The resulting
fragility functions are essential to evaluate direct losses due to multiple hazards, i.e. physical
damage, as a means to deliver the Quantitative Risk Assessment (QRA) of the exposed bridges
and networks. The framework is extended to the transport network level exposed to multiple
hazards, providing a mean for allocating the resources reasonably toward efficient management
and consequence analysis.
economies and societies. Therefore, resilience assessment of infrastructure assets to extreme events and
sequences of diverse hazards is of paramount importance for maintaining their functionality. Yet, the resilience
assessment commonly assumes single hazards and ignores alternative approaches and decisions in the
restoration strategy. It has now been established that infrastructure owners and operators consider different
factors in their restoration strategies depending on the available resources and their priorities, the importance ofof multiple hazards and their impacts, the different strategies of restoration, 29 and hence the quantification of
resilience in that respect exists and this is an acknowledged gap that needs urgently filling. This paper provides,
for the first time in the literature, a classification of multiple hazard sequences considering their nature and
impacts. Subsequently, a novel framework for the quantitative resilience assessment of critical infrastructure,
subjected to multiple hazards is proposed, considering the vulnerability of the assets to hazard actions, and the rapidity of the damage recovery, including the temporal variability of the hazards. The study puts forward a well-informed asset resilience index, which accounts for the full, partial or no restoration of asset damage between the subsequent hazard occurrences. The proposed framework is then applied on a typical highway
bridge, which is exposed to realistic multiple hazard scenarios, considering pragmatic restoration strategies. The case study concludes that there is a significant effect of the occurrence time of the second hazard on the
resilience index and a considerable error when using simple superimposition of resilience indices from different hazards, even when they are independent in terms of occurrence. This potentially concerns all critical infrastructure assets and, hence, this paper provides useful insights for the resilience-based design and management of infrastructure throughout their lifetime, leading to cost savings and improved services. The paper concludes with a demonstration of the importance of the framework and how this can be utilised to estimate the resilience of networks to provide a quantification of the resilience at a regional and country scale.
