| Outline of Final Research Achievements |
Soft-first story structures such as pilotis buildings are known as vulnerable structures against earthquakes. In case of such buildings, the first stories of the buildings suffer destructive damages during strong earthquakes. In this research, semi-active seismic response control system is applied at the first story of the buildings.
Through the pseudo-dynamic tests of on shear and flexural reinforced concrete columns, we proposed a simplified method to predict maximum response deformation using a seismic momentary input energy.
The bending shear scaled model to simulate the vibration properties of soft-first story structure was constructed and discussed a simple control method of the damping force in a magneto-rheological fluid damper subjected to overall flexural deformation response. The response reduction of this scheme was confirmed through the shaking table tests.
