A novel combination of structures for connected-control mechanism (CCM) has been presented. By coupling base-isolated and ordinary structures, the vibration suppression effect of CCM is expected to be expanded. Experimental structures and CCM mechanism using magnetic dampers were built and excitation experiments were carried out. In the previous study, however, the achieved vibration suppression performance was not satisfactory. In study, to enhance the performance, spring elements are introduced. The spring constants are tuned according to so-called “fixed-point theory” The performance of the designed system is investigated experimentally.

The connected control method (CCM) utilized reaction force between buildings as damping force by using connecting springs and dampers. The effectiveness of CCM has already been established in previous studies. In this paper, bidirectional internal connected control method (BICCM) with an experimental high-rise building split into four substructures is presented for a vibration control method to mitigate structural vibration by using internal damping force by CCM. Therefore, IBCCM is expected that is effective method for a high-rise building against large earthquake excitation. In this report, the effectiveness BICCM is investigated through computer simulations
