| Outline of Final Research Achievements |
Using the modeling of the seismic source process based on the Tohoku Earthquake and the latest propagation path and site characteristics from the observed records, the quantitative broad-band seismic motions were predicted. Then nonlinear response of a long-period building was calculated by a three-dimensional frame model to obtain the functional damage potential. Based on the experiments of indoor furniture using a long-period shaking table, the relationship between floor response and indoor damage was established. Damper as an earthquake-resistant reinforcement for reducing functional damage potential was put into practical use through the shaking table test of a model structure and the field observation of a real steel frame. Finally we studied soft countermeasures assuming damage prescribed above. We integrated the above results and conducted studies on the life continuity plans and evacuation plans with evacuee predictions that minimized the impact of expected functional damage.
