Abstract
In late years, large scale earthquakes are occurring in the world. Then, control of seismic response of house is important for protection from destructive earthquakes. This paper proposes some types of oil dampers for vibration control device for two story houses. Oil damper is connected to the ceiling of the first story and fixed on the foundation. The rectangular parallelepiped damper, the cylindrical damper and the spherical damper with silicon oil are proposed. The effectiveness of oil dampers is examined by experiment and simulation. It is concluded that the peaks of the resonance curve are reduced when dampers are used.
