• The detached houses, in general, have the first natural frequencies in relatively higher range, and their structural deflection is small even though their response acceleration is high. Therefore, the deformation transmitted to damper becomes small, and the dampers have to be designed to obtain a desirable performance against such small amplitude vibrations. For this reason, the new type of damper having the displacement amplification mechanism was developed to solve this problem in this study ("pipe-type-damper"). This paper reports on the results obtained from experiments and analysis of a detached house model using the dampers. In the experiments, the trial damper of 10kN capacity was made, and the experiments were performed to investigate the fundamental characteristics of the pipe-type-damper. As a result, the properties of the pipe-type-damper were expressed by the fractional derivative 3-element model, its restoring force was proportional to the second power of amplification factor by the amplification mechanism. Analytical results obtained by considering the characteristics of damper showed that the pipe-type-damper had good vibration control performance.
