Based on the experimental studies of the dampers, it was indicated that the force displacement hysteretic curves were very full, and damping ratios were great. The dampers were velocity dependent. The damping force and velocity relation was nonlinear in lower velocity region, and was approximated by Bingham model in higher velocity region. The controllability of the dampers was dependent on the viscosity and shear yield strength of the magnetorheological fluid and the magnetic field strength inside dampers.
