WebJun 1, 2024 · The main objective of this paper is to provide a framework for the fragility analysis of bridges under single and combined multiple hazards, based on detailed numerical modelling of bridges exposed to flood effects (scour, hydraulic forces and debris accumulation) followed by seismic shaking. 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.
