| Outline of Final Research Achievements |
We have investigated the characteristics of tsunami wave force acting on structures in a town. The aim of this study is to establish an estimation method of the tsunami wave force generated by collision of tsunami wave to structures.
In the case of the isolated structure, it was found that the generation of the vortex in front of the vertical wall affects to the pressure distribution. However, it depends on the configuration of the structure. The maximum pressure acting on the building inside the town including the multiple buildings could be estimated by using the ratio of the sea side building area to the whole town area.
