| Outline of Final Research Achievements |
This study aims to develop a seismic device for mid- and low-rise buildings, mainly for Japanese typical wooden houses. The device works to prevent soft-story mechanism of buildings under severe seismic ground motions, which is extremely effective to reduce loss of human life due to earthquakes. First, we formulate the mechanical model of the device and conducted a series of analytical study to verify the effectiveness of the device. Then, the details of the device are decided through the dynamic loading tests on full-scale wooden frames and the shaking table tests on scaled building frames with/without the devices. It is confirmed in this study that the proposed seismic device is quite effective to enhance the seismic performance of buildings.
