Flood fragility analysis of instream bridges
WebAbstract. Floods, bridge scour, and flood-associated loads have caused over sixty percent of bridge failures in the U.S. Current practices for the vulnerability assessment of … WebApr 10, 2024 · The presence of a bridge structure in the river induces changes in the natural geometry of the river cross section by, therefore, altering the hydraulic regime significantly and causing the so-called backwater effect. Nevertheless, the effect of the bridge configuration on the hydraulic regime is barely studied. Therefore, the main …
Flood fragility analysis of instream bridges
Did you know?
WebThe stochastic bridge responses obtained using HDMR metamodels are further utilized to develop fragility functions for the flood loading. Novelty of the present study is in the application of the HDMR in estimating stochastic bridge responses under flood loading and in developing flood fragility functions using the HDMR metamodel. 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-
WebFlood fragility curves can be used as an objective tool to assess the risk of a bridge to exceed some limit-states for a given flood. Despite the method’s extensive use in seismic reliability analysis for civil infrastructures, the approach has rarely been utilized in evaluation of scour critical bridges.
