| Outline of Final Research Achievements |
In the present study, it has aimed to evaluate damage and the damage situation when a huge long-period ground motion acts on the high rise building, and to propose the damage reduction measures with a vibration control device.
The accumulation plastic strain magnification and the experimental methodology of the edge of the beam were investigated. The vibration control reinforcement that partially established the oil damper and the steel-made damper in the lower layer part was proposed. A high vibration control performance was confirmed from the response analysis results. An analytical model considering the performance decrease index of the vibration control damper by the repetition for a long time was built. The response considering the performance decrease by the seismic response analysis was evaluated. The response considering the performance decrease by using the response analysis results was evaluated.
