摘要：

The procedure of improving the structures damping performance was proposed by interconnecting two structures with a connecting member consisting of a spring and a damper. The modal equations of the: first mode of both framed structures interconnected were shown using equations for the motion of a two-degrees-of-freedom (2d.o.f.) system, with two masses and three springs. The tuning method of a connecting element in the above 2d.o.f. system, by which the damping performance of the two systems in the 2d.o.f. system was equalized and maximized, was proposed, and the approximate tuning method of the connecting member, by which the damping performance of the first mode of the two Framed structures interconnected was equalized and the maximized, was proposed using the tuning method of a connecting element in the 2d.o.f. system. In numerical investigations, the usefulness of the approximate tuning method and the effectiveness of the interconnecting member were shown. (C) 2001 Academic Press.
