In this study, the structural fragility of a bridge structure due to a tsunami wave load is evaluated, quantitatively analyzing the damage data of bridge structures due to the 2004 Tsunami in Sri Lanka and in Indonesia, which are on basis of 58 data on Sri Lanka and 17 data on Sumatra. By the formulation of a fragility curve of a bridge structure from statistical analysis of the data, the structural fragility of a bridge structure due to a tsunami wave load, which describes the relation between the tsunami damage classification of a bridge structure and a tsunami wave load such as inundation depth and inundation height, is revealed.
