Abstract
To evaluate the wave force to the bridge by the tidal wave, the experiment was executed. We measured the wave force, the lift force and the wave pressure in the experiment. We compared the equation of the wave force drived Goda or Asakura with the measured wave force. The wave pressure drived the measured wave force greatly exceeded the wave pressure drived Goda or Asakura by the situation. The lift force was 3.0 times as large as the wave force, and we should consider the lift to the design of the bridge.
