| Research Abstract |
The authors made a reconnaissance survey on the 25 bridges out of 83 bridges, which observed in Sumatra island. It was found that most of damage of bridges can be classified into two types such as lost of girders and scour around retained abutments. Next, to evaluate the tsunami force to the bridge, the experiment was executed. The wave pressure driven from the measured wave force exceeded the wave pressure driven from Doda or Asakura equation. Especially, the lift force was 3. 0 times as large as static water pressure.
