Outline of Final Research Achievements

In the 2011 off the Pacific coast of Tohoku Earthquake, many bridges lost their functions due to outflow due to tsunami not expected in the seismic design.
It is important from the viewpoint of disaster mitigation to develop a technique to prevent fatal damage.
This study was conducted to construct a method for evaluation the washed-away bridges affected by the tsunami and a technique for improving functional recovery.
