Interconnection of the neighboring structures using a member, consisting of a spring and a damper, is an improvement method of damping performance of structures. When the first mode displacement is adopted as the displacement in free vibration state, interconnected strcture system is become a two-degrees-of-freedom (TDOF) system with two masses and three springs cnnected in series. The maximizing method of damping performance of the above TDOF system can be used for maximizing the damping performance of the structures interconnected. In this study, a rigid frame with one story was adopted as a structure. The theoretical tuning method of a connecting member, by which damping performance of rigid frames is maximized, was verified experimentally and the effectiveness of tuning method became clear.
