Interconnection of the neighboring structures using members, consisting of a spring and a damper, is an improvement method of damping performance of structures. When the first mode displacement of structures is adopted as the displacement in free vibrating state, interconnected structure system consisting of three structures is become a three-degrees-of-freedom (3DOF) system with three masses and five springs connected in series. The maximizing method of damping performance of the above 3DOF 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 structural model. 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.
