Flow of tsunami past a section of a concrete girder bridge has been simulated by using a Large Eddy Simulation (LES) technique. The forces and moments on the fixed or simply-supported girder due to the flow were evaluated and the motion of the bridge deck, assumed to be a rigid body, is solved simultaneously with the flow. The force results on the fixed deck agree with previous studies. The initial motion of the bridge deck was found consistent with the implication of the survey of the site of the failed bridge and accounts of the observers and the video images.
