Flood fragility analysis of instream bridges
WebThe study combines a uid dynamics model with a structural analysis model to assess the performance of an inundate bridge and then assess the impact on the functional-ity of the surrounding transport network. The paper lacks of basic bridge engineering understanding and bridge modelling and therefore has inaccuracies and provides lim- WebFeb 7, 2024 · Therefore, this study proposes a new approach for bridge flood fragility analysis. To obtain accurate flood fragility estimates, reliability analysis is performed in conjunction with finite element analysis, which can sophisticatedly simulate the structural response of a bridge under a flood by accounting for flood-related risk factors.
