Outline of Final Research Achievements

A strong motion prediction technique was developed, including the long period ground motion due to each individual local region. The study was focussed on the long period-spectral characteristic derived from deep ground configuration of region, which is generally verified in strong ground motion records. The technique was applied to the Noubi Plain of the Kanto, Tokai, and Osaka districts.
The research was extended to the breakthrough on the relation between the ground motion duration and fatal damage of several types of structures. The strong degree of dependence of soil structures on the ground motion duration was quantitatively demonstrated.
