The authors have developed a new steel plate damper with honeycomb-shaped openings which has been applied to actual buildings. This study was undertaken in order to understand its restoring force characteristics and energy absorption capacity when subjected to low cycle fatigue, as corresponding to differences in damper size, grade of steel and the amplitude of horizontal displacement, in order to broaden its range of applications. Fourteen specimens were cyclically loaded. The conclusions obtained from the results of the tests are summerized as follows. a) Differences in damper size do not influence either the restoring force characteristics or the fatigue life of the dampers, if they are in similar configurations. b) The relationship between the amplitude of horizontal displacement and the fatigue life of a damper can be estimated using Coffin-Vanson's formula. c) The fatigue life of a damper loaded with various amplitudes of sway deformation can be predicted using Miner's Law.
