Abstract
In this study, firstly, we clarified force to act on a bridge girder under steady flow by physical experiments. Next, we calculated velocity to act on the bridge girder by tsunami run up analysis using STOC, and predicted the damage of bridge girder. From the result of the physical experiment, we suggested a formula for computation of a drag coefficient and the lift coefficient under conditions of the steady flow. We performed tsunami run up analysis for bridges of the tsunami inundation area to get velocity to act on bridge girder and water level elevation.We performed the damage prediction of the bridge by empirical formula of a drag coefficient and the lift coefficient and velocity by tsunami going up analysis. As a result, the predictive precision improved more as a result of past by using this technique.
