In this paper, the energy absorption capacity of a hysteresis damper installed in a damage control structure was investigated. The performance of a hysteresis damper is limited by its fracture. The method predicting the metal fatigue life is extended to apply to the evaluation of the life of dampers. However, the method based on the energy absorption is necessary for the earthquake-resistant design. The conclusions obtained from this paper can be summarized as follows. (1) The energy-based method to evaluate the ultimate performance of a hysteresis damper was proposed based on the results of the cyclic loading tests. (2) The characteristic of the distribution of the energy response of the damage control structure is clarified based on the results of the earthquake response analyses. (3) By using these results, the simple method to predict the energy absorption capacity of the damper was proposed.
