This study proposes a dynamic characteristic of Linked Fluid Inertia Mass Damper (LFIMD) for deflection distribution control of three-story structures. The damper consists of three oil dampers linked. This damper making it possible to control the story deflection by moving linked three piston rods. First, we study the basic dynamic characteristics of the damper. The dynamic loading test shows that the damper exerts high linking stiffness and stable viscous damping. Secondly, we calculated dynamic characteristics of LFIMD by taking the characteristics of a damper (FIMD) obtained from experiment. Finally, analytical study shows that can control story deflection efficiently. Using this system, we are able to reduce installation radix of damper without decreasing link stiffness.
