Abstract

In the Tohoku-Pacific Ocean Earthquake, many bridges were washed away by the tsunami. In the future, countermeasure for tsunami disaster will be needed, and the evaluation of tsunami wave force acting on bridges will be very important. This paper discusses the hydrodynamic tsunami-induced force acting on a bridge superstructure based on hydraulic model experiments. The results showed that tsunami wave forces were different according to the shape of tsunami incident wave and it was confirmed that maximum wave forces could be expressed by a function of the wave front slope of tsunami incident wave.
