116 Research and Development of Vibration Control Device for Detached House by Using Displacement Amplification Mechanism

Abstract

In recent years, the vibration control devices for the detached house has been attracted attention. However, the detached house has the first natural frequency at high frequency band. Therefore, the deformation transmitted to damper becomes small, and the damper have to be designed to obtain a desirable performance against such small amplitude vibrations. Moreover, the cost of manufacturing dampers should be lowered to be used widely. In this study, the damper using the amplification mechanism has been developed to address the above issues. The experiment was performed to investigate the property of the damper, and the earthquake response analysis based on the restoring force characteristics of experimental results was carried out to evaluate the performance of the damper.
