20.500.12556/DiRROS-16087 Flood vulnerability study of a roadway bridge subjected to hydrodynamic actions, local scour and wood debris accumulation The increased occurrence and intensity of flooding events have represented a real threat to bridge reliability and end-user safety. As flood vulnerability assessment is a valuable tool for enhancing the resilience of bridges to climate change, it is of interest to push the development of such methods. To this end, a computationally efficient methodology to assess the flood vulnerability of a bridge was developed and implemented in a case study. A particular focus was devoted to modelling wood debris loads on the bridge pier, for which two different approaches were implemented. The first is a standards-based approach, whereas the second is based on up-to-date research data. The results indicate that the second approach is less conservative as it leads up to a 40% higher exceedance probability for the considered limit states. The interaction between wood debris loads and local scour was also examined and proved to have a relevant impact on the vulnerability of the bridge. These results highlight the shortcomings of the existing standards in providing accurate results. It is perceived that not only will the new quantitative tool be valuable in ensuring optimal bridge design, but it will also be beneficial for assessing bridge risk mitigation measures. flooding vulnerability wood debris local scour hydrodynamic load stochastic approach bridges open access poplave ranljivost naplavine erozija temelja hidrodinamična obtežba stohastičen pristop mostovi odprti dostop true false true Molecular Diversity Preservation International - MDPI Angleški jezik Slovenski jezik © 2022 by the authors.
