APPLICABILITY OF MANUAL
Four types of devices are considered in the manual. They are oil dampers, viscous dampers,
viscoelastic dampers, and steel dampers such as shown in Fig, 1.
Viscous damper produces the hysteresis loop of combined ellipse and rectangle. The material
used therein is typically silicon fluid, and its resistance against flow produces the damper force. The
damper possesses configurations of vertical panel, box, or cylinder.
Oil damper produces the hysteresis loop of ellipse. The material used therein is oil, and its
resistance against flow at orifice produces the damper force. The damper possesses the
