The optimal allocation of damping in coupled buildings and its control efficiencies are discussed in this research. For a given total damping, the optimal connecting damping and connecting stiffness that result minimum magnification factors for stable vibrations are searched from numerical computation. It was found that allocation of total damping for connecting damping gives maximum control efficiencies when the total damping is smaller. While for larger total damping, the required connecting damping decreases, and more damping should be allocated within buildings. The efficiency of coupling decreases with the increase of total damping, and is defined by an equivalent damping factor. Using equivalent damping factor and equivalent vibration periods, earthquake response of the coupled buildings may be satisfactorily evaluated by response spectra of single degree freedom system.
