New passive damper device with high damping rubber was developed. Static shear loading test and shaking table test of a wood frame which the damper device was installed were conducted. The initial shear stiffness was higher than the one of conventional shear resisting element, such as plywood or wood brace. The hysteresis loop of the wood frame with the damper device was stable even under cyclic load. Moreover, a structural model of a wood frame with the damper device for earthquake response analysis was constructed. It was found that the simulated response motion of the wood frames with the dampers was in good agreement with the measured response of them obtained from the shaking table test. In the analysis of various combinations of conventional shear resisting element and the damper device, it was also found that the more damper is installed, the less response displacement become. This result is based on the feature of the high damping rubber used for this damper.
