OS09F044 Vibration analysis of reduction for seismic response of system using friction bearing

抄録

A new device of reduction for seismic response using friction bearings was developed. In this paper, dynamic characteristics of isolated plate using this device were investigated by vibrations tests by artificial time histories. The peak acceleration amplitude on isolated plate has decreased to about 50-90%. Although a spectral peak around 0.5 Hz that is natural frequency of isolated plate was identified, the amplitude of spectral peak was decreased using bearing with high friction. This device is useful for reduction of seismic response.
