Evaluation of a Tsunami Wave Load Acting to a Deck of a Road Bridge

Abstract eng:
A giant earthquake of Magnitude 9.1 and the induced tsunami caused the catastrophe in the countries surrounding the Indian Ocean in December 26, 2004. One of the main reasons of the damage is that infrastructure systems such as road structures and related utilities were affected severely by the tsunami wave load as well as masonry and wooden houses. Thus, in this study focusing onto the tsunami damage of a road structure, the hydraulic experiments were carried out to clarify a tsunami wave load acting to a road structure. Focusing on a simple spanned concrete bridge among various structural types of road structures, the dependence of the damage of a bridge deck on a tsunami wave load such as inundation height is revealed.
