    This study proposes a method for controlling seismic response of structures using a Linked Fluid Inertia Hass Damper (LFIMD). The damper has three distinguished mechanical properties; they are the damping effect by viscous fluid, the inertia force by moving fluid at high velocity and the ability to make structural deflection distribution quite uniform by hydraulic link system. In this paper, we first explain how the proposed damper works by basic performance test on a LFIMD. It is confirmed that a mechanical model exactly simulates the experimental results. And then we analytically show how we use the damper to reduce deflection, acceleration and damage concentration to any specific part of structure by making use of LFIMDs. From above, we conclude that seismic response control with LFIMDs is more effective than with existing damping devices.
