Details	Many types of elastoplastic dampers have been developed to suppress the vibration of buildings and piping systems during earthquakes. These elastoplastic dampers are one-way or two-dimensional dampers. In this paper the authors propose a three-dimensional elastoplastic damper using four semicir-cular metal rods. The trial damper was made, and its resisting force characteristic was discussed analyti-cally and experimentally. Next, an experimental model of a one-story detached house having the elas-toplastic damper was also made, and the seismic responses of the house model were measured using a permanent magnet-type shaking table. The experimental results were compared with the calculated re-sults, and the propriety of the calculations was confirmed
