During large earthquakes, a mutual reaction force type vibration control method is effective to control the vibration of high-rise buildings. This is a method of promoting interaction between control force and reaction force by connecting two stuctures with a damper. In this paper, we present an optimal frequency adjustment method and an optimal damping of connected double frame structures. Using either spring devices or levers with additional masses at the connecting part, it is possible to make the transfer function peaks of both structures equal and lowest. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
