As the performance-based design is coming to be widely used for earthquake-resistant buildings, it would be more necessary to evaluate the building performances through earthquake dynamic responses. Hysteretic dampers are popularly installed in high-rise buildings in ordert to control the earthquake responses. In this paper, we propose a simple method to optimize hysteretic-damper strengths so as that the story-drift responses are distributed with the targeted value equally for all storys of a building under earthquake excitations. The applicability of the method was demon-strated by a numerical calculation of various frame models through a nonlinear frame analysis.
