| Outline of Final Research Achievements |
The critical excitation methods have been developed mainly for random earthquake ground motions except long-period ground motions which were observed during the 2011 Tohoku earthquake. The criticality of the long-period ground motions is focused in this project. Because it seems difficult to respond to unpredictable earthquake ground motions only with the consideration of ground motion uncertainty, the structural design method including both ground motion uncertainty and structural robustness (redundancy) has been proposed in this project.
