The research integrates inertial elements with water tanks to develop inerter-based multi-tuned liquid column dampers（MTLCDI）for mitigating wind-induced vibration of linked high-rise buildings. MTLCDI not only exploits functions of the water tanks installed on each high-rise building for daily water supply and firefighting，but also utilizes mass amplification effects of inertial elements for wind-induced vibration control. Non-linear governing differential equations of motion are formulated to model MTLCDI controlling wind-induced responses of linked high-rise buildings，and the equivalent linear method is verified to solve the non-linear equations. Linked high-rise buildings are adopted as a case to investigate the control effects of MTLCDI on the buildings excited by wind loads obtained from wind tunnel tests. The mitigation effects of optimal MTLCDI installed on the linked high-rise buildings are compared with those of three other devices（i.e.，TMDI，MTMDI，and TLCDI）. It is found that MTLCDI is more effective to reduce wind-induced acceleration，fluctuating displacement，and inter-story drift ratio of the buildings. Besides，MTLCDI also takes advantage of the water tanks and saving installation space of each building. These findings can be useful for the wind-induced vibration control design of linked high-rise buildings.
