Severe vibration of underground structures may be induced under blast loads.According to the characteristics of the explosion-induced ground shock wave,a new-type damper,inverse control magneto-rheological(MR) damper was designed to control the vibration.The high-frequency performance test of the MR damper was carried out on the small shaking table.It is shown that the performance can be modeled by use of the modified Bouc-Wen model,and the pa rameters of the model keep stable in the range of 15-50 Hz.
