| Outline of Final Research Achievements |
This research proposes a concept that, for the seismic design, not a few strong ground motions, but a whole set of input ground motions should be considered. To implement this concept, we developed a scheme to determine the set of ground motions in which their value in terms of their effect on the seismic performance of the structures are evaluated by information entropy. Also proposed a practical method to synthesize the ground motions that represent the set of ground motions, in which a candidate of input motion “learns” other waves to grow a representative wave to be considered in the seismic design. The develop method uses Jensen-Shannon divergence for stable computation of information quantity and utilizes clustering method to deal with a wide range of ground motions efficiently.
