A coupled vibration control is a method for reducing earthquake responses by connecting buildings with different periods using dampers. In this paper, two single-degree-of-freedom systems connected with a hysteresis damper are used for the vibration model. The objective of this paper is to reveal the general characteristics of coupled vibration control structures analytically. The criteria of the response control effect is the reduction of the deformation of the buildings. The condition of optimum damper and the relationship between the response control effect and the combination of building are investigated. By comparing the deformation of the buildings connected with the optimum damper to that of the rigidly connected buildings, the equation to predict the effect of vibration control can be obtained.
