A new vibration control system is proposed for residential houses. This system consists of braces and a damper unit including a high-hardness tubber damper. Post tensioning forces axe introduced into the braces to reduce small gap in joint parts and this system has high damping performance for micro-vibration. The control system can absorb sufficient energy through the high-tubber damper and post tensioning braces. A concept is introduced called an effective deformation ratio, i.e. the ratio of the actual damper deformation to the interstory drift of the frame as a criterion to measure the damping performance and effectiveness of this system. To find out principal parameters that affect greatly the effective deformation ratio of the proposed new vibration control system, two simple analysis models axe proposed that can simulate the main characteristics of this vibration control system.
