This paper presents a construction experiment of a stud-type damper using shear panels and a loading test of a fullscale steel frame reinforced by the damper. First, ways of connecting the damper to existing beams or concrete slab are proposed. Secondly, the construction experiment and the loading test were conducted. Test results are summarized as follows ; (1) the damper was placed on the steel frame without any difficulty, (2) the hysteresis loops of the specimen were stable up to the loading cycle of 0.02 rad and the specimen formed collapse mechanism as expected, (3) connections between the damper and beams did not collapse through the loading test. Finally, it is verified that the stiffness and yield strength of the damper can be predicted very well by the presented mechanical model.
