Abstract
A new oil damper for reduction of seismic response of two story house is developed. Oil damper contains silicon oil and some shapes of materials. Oil damper is connected to the ceiling of the first story and the foundation of house. First, the effect of oil damper is examined experimentally. Spherical damper and cylindrical damper are used in experiment. It is found that peak of the resonance curve is reduced when the dampers are used. Next, two story house with the damper is modeled as a two-degree-of-freedom system. Using actual earthquake records, the response of the house is obtained. It is found that the maximum response is reduced when the dampers are used.
