A novel framework for the expedient assessment of flood risk to transportation networks focused on response most critical and vulnerable infrastructure assets, bridges, is developed, validated applied. Building upon recent French guidelines scour (CEREMA, 2019), this paper delivers a thorough methodology, that incorporates three key, parameters: (i) hydrodynamic loading, hazard component equal significance scour, hazard; (ii) correlation select indicators with new index relating flow velocity, primary measure adverse impacts flow–structure interaction, enabling more accurate automated, bridge susceptibility scour; (iii) use new, comprehensive indicator, namely Indicator Flood Hazard Intensity (IFHI) which incorporates, in simple yet efficient way, key parameters controlling severity impact floodwater height, obstruction, sediment type.

Traffic Hazards on Main Road’s Bridges: Real-Time Estimating and Managing the Overload Risk

IEEE Transactions on Intelligent Transportation Systems, Год журнала: 2024, Номер 25(9), С. 12239 - 12255

Опубликована: Март 12, 2024

The risk associated with extreme traffic loads on bridges has seldom been explored, State-of-the-art evaluation methods being time-consuming and unsuitable for fast management. Traditional management advocates optimizing offline bridge maintenance plans. In contrast, novel approaches that can assess manage this live through Intelligent Transportation Systems (ITSs) are lacking. This study addresses these gaps a three-block framework. It utilizes Weigh-In-Motion (WIM) systems collecting bridge-specific load data, develops probabilistic Risk Prediction Model estimating the frequency severity of overloading events drawing current Structural Design Codes (SDCs), simulates an ITS-based architecture implementing actions. framework was tested 2.5M $+$ WIM raw data records gathered from ring road Brescia, Italy. Results showed design were overcome more frequently than SDCs prescriptions, violations Traffic Code mass limit significantly affected predictions. These findings underscore need increased attention when issuing permits extremely overweighted vehicles encourage enforcement strategies implemented by architectures real-time

An assessment of priorities in handling climate change impacts on infrastructures

Scientific Reports, Год журнала: 2024, Номер 14(1)

Abstract Climate change (CC) will likely significantly impact the world’s infrastructure significantly. Rising temperatures, increased precipitation, and rising sea levels are all to stress critical infrastructures (CI). temperatures can lead damage from extreme heat events. This cause roads bridges buckle or crack, leading costly repairs potential traffic disruptions. In addition, waves vital electrical infrastructure, widespread power outages. light of this context, article reports on a study which examined connections impacts CC infrastructure. The employed mixed-method approach, combining bibliometric analysis for period 1997–2022 with series relevant case studies five continents offer insight into fills research gap in respect assessments extent climate negative influences special focus developing countries. It also showcases CI projects adaptation measures being currently deployed, address CC. results show that current is vulnerable selected industrialised countries, there perceived need understand better areas such as transport, settlements, coastal order protect impacts, governments invest flood control, early warning systems, improved building codes.

Bridges and critical transport infrastructure are primary assets systems that underpin human mobility activities. Loss of bridge functionality has consequences on entire networks, which also interconnected with other networks. Cascading events then unfold in the system systems, leading to significant economic losses societal disruption business society. Recent natural disasters have revealed vulnerabilities bridges diverse hazards (e.g. floods, blasts, earthquakes), some exacerbated due climate change. The assessment network by quantifying their capacity loss adaptation new requirements stressors is thus paramount importance. aim this work was try understand main compound hazards, threats short- long-term impacts structural impact closures operability. drivers restoration reinstatement were considered. performance, driven redundancy robustness a bridge, first step be considered overall process resilience quantification.

Strategic assessment of bridge susceptibility to scour

Reliability Engineering & System Safety, Год журнала: 2024, Номер 251, С. 110334 - 110334

Scour-induced failures of bridges pose a global challenge, leading to significant economic and service losses. Compounded by infrequent inspections inadequate consideration hydro-geological factors in current scour risk assessments, this issue is particularly pressing the context climate change associated hazards. Addressing imperative for enhanced infrastructure resilience, study introduces framework management. Utilizing Geographic Information Systems (GIS) datasets applying Analytic Hierarchy Process (AHP) assess various weighted affecting risk, we have systematically mapped information layers encompassing structural, riverine, geological, flood conduct strategic susceptibility assessment. The proposed approach applied railway network southeast England, identifying scour-susceptible that can be prioritized detailed inspections. Compared existing scores, scores approximately 30 region were adjusted, with 22 transitioning from medium high priority. Our methodology, exemplified case study, offers asset managers deeper insights into determinants facilitates informed decision-making prioritizing scour-mitigation measures across network.
