Through the experiment, the mechanical model of the damper was established. The damper was installed on a five-story steel frame model and simulated earthquake shaking table test. Different control algorithms are used in the experiment and different seismic waves are input. The experimental results show that this kind of damper can effectively control the seismic response of structures. Finally, the seismic response of the viscous damper control structure is simulated.
