Outline of Final Research Achievements

In this study, the characteristics of the seismic performance required from the view point of post-seismic functionality was investigated, based on lessons from the damage of recent earthquakes such as the Great Hanshin-Awaji Earthquake. The seismic performance was defined by the design basis earthquake magnification at the limit recovery time. In order to analyze the characteristic of the performance, we compared the level of the seismic performance with that of the safety performance which is currently required. As a result, it was revealed that the seismic performance for significant and large buildings, in which ductility design is adopted, tends to become smaller than the safety performance, indicating that the performance should be considered in seismic design to prevent opportunity loss expected at large earthquake in the future.

Academic Significance and Societal Importance of the Research Achievements

最近の地震被害において建物の地震後継続使用に支障をきたすケースが多く報告されている。建物の機能停止による損失は、都市の規模拡大や経済活動の活発化に伴い大きくなることから、都市の成長とともに今後益々増大することが考えられる。しかしながら限界機能停止時間から決定される耐震性の現状を明らかにした研究はこれまでにない。事業継続性の観点から、経済活動を支える事務所用途や住居用途建物の耐震性の現状を知ることは重要である。
