| Outline of Final Research Achievements |
Many bridges were damaged due to the tsunami that followed in the wake of the 2011 Great East Japan Earthquake. A tsunami has such a great power as destroying bridges. When bridges washed away by a tsunami, the damage causes loss of valuable social capital and delays of rescuing people and supplying goods. This project aimed to improve safety of bridges against tsunami and floods. To accomplish this, the following topics were studied; 1. numerical simulation methods to evaluate hydrodynamic forces to bridges, 2. effects of side fairings on tsunami induced loads to prevent washout of bridges, and 3. structural health monitoring system after tsunami and floods.
