Abstract
The aim of this paper is to show the effect of the Joint Damper System (J.D.S) through both experimental and analytical approaches. For these experiments, full-scale frame structures and a variable damper device which is controlled to perform the idealized viscous damper device, are used. As a result, it is shown through earthquake excitation tests that there are optimal damping coefficients for the joint damper. It is also shown that the control effects of JDS differ in accordance with the characteristics of the input earthquake excitation and structural parameters.
