| Outline of Final Research Achievements |
The purpose of this project is to develop effective countermeasures of high-rise buildings by considering broadband strong ground motions for hypothesis large earthquakes under the Tokyo metropolitan area and along the Nankai Trough. We simulated seismic response of the Shinjuku Campus Building of Kogakuin University (29 floors of steel-frame, located in Shinjuku, Tokyo), and proposed a cost-effective arrangement of the seismic retrofitting using energy dissipating dampers. In addition, we developed an effective earthquake resistant fixing metal to prevent falling of ceiling boards of office buildings during strong shaking, and confirmed its effectiveness using shaking table tests. Finally, we checked the structural monitoring system, which shows safety checking results in the emergency control room in the high-rise building, immediately after an earthquake, and confirmed its effectiveness through emergency drills.
