Response Control Effect of Coupled Vibration Control Structures Using Hysteresis Damper under Ground Motion

Abstract eng:
"Coupled vibration control structures" 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 are the reduction of the deformation of the buildings. The optimum damper conditions and the relationship between the response control effect and the combination of buildings are investigated. By comparing the deformation of the buildings connected with the optimum damper to that of rigidly connected buildings, equations to predict the effect of vibration control can be obtained.
