Abstract Fragility curves are developed for the reinforced concrete girder bridges under flood hazard in Lockyer Valley Region in Queensland, Australia. A failed bridge structure during 2011 severe flood event has been case studied in this paper. Uncertain nature of flood intensity for a given catchment area that causes random flood induced forces to the bridge structure and the variability of its geometry and concrete material strength are all taken into consideration in deriving these fragility curves. The fragility curves show that the probability of damage on bridges is much higher when it is subjected to urban flooding associated with log impact loading than that of being under a rural flooding. The results verify the AS5100 code provision for flood loading on to the bridges.
