Abstract
Reduction of seismic response of house is an important problem for aseismic design. In this paper, spherical damper, cylindrical damper and rectangular parallelepiped damper with silicon oil is developed for reduction of seismic response of two-story house. For reduction of seismic response of two-story house, an oil damper is connected to the ceiling of the first floor and the foundation. Resonance curves are obtained for various coefficient of kinematic viscosity of silicon oil. Peak responses in resonance curves are focused on. Damping ratio and peak amplitude ratio for the first vibration mode are obtained for various forms of damper. It is found that the peak responses are reduced when dampers are used.
