| Outline of Final Research Achievements |
This study developed the 3 dimensional(3D)inelastic earthquake and tsunami response simulation method of industrial and civil infrastructures on the basis of theoretical method using a seismological model. In this method, the 3D input earthquake ground motions and tsunami waves at the structural sites are simulated by the seismological model, and then the 3D inelastic earthquake responses are carried out and the earthquake damages of structures are evaluated. Finally 3D tsunami inelastic responses of the damaged structures due to earthquake are performed and the structural damage processes due to the earthquake and tsunami waves are evaluated. Using this method, the damage processes of the bridges and the storage tanks are examined and it is found that the bridge damage is mainly caused by the tsunami waves only but the damage of storage tanks is resulted from both earthquake ground motions and tsunami waves and the damage expands by the tsunami waves.
