Mechanical Behavior of Stud-type Damper using Steel Shear Panels
Shintaro MATSUO, Yusuke SAKAI, Kazuo INOUE
This paper proposes a new stud-type damper using steel shear panels. This damper is available for both newly constructed steel buildings and existing steel buildings. In this paper, a simplified model for static or dynamic response analysis is proposed. This model is composed of two elasto-plastic rotational spring and elastic member which deforms axially. The test results clearly reveal that the hysteresis loops of the specimens are stable up to 0.02 rad and that the shear panels have enough plastic deformation performance. It is also verified that the stiffness, strength and amount of shear deformation of the damper can be predicted very well by the presented mechanical model.
