Abstract
An active mass damper(AMD) for controlling wind-induced vibration of a building structure determines its control force according to a control algorithm and the measured structural responses. One of the important design factors in application of the AMD is to design the AMD to show good control performance in spite of minimizing its mass, motor torque, and stroke. In this study, a technique was proposed to minimize the stroke and mass of the AMD and assure its control performance. Gain scheduling for the control force and constant-velocity signal directing the AMD go backward to its zero point were presented. Also, a band-pass filter was used for eliminating the spill over effect due to the higher mode. The effectiveness of the proposed method was first analytically verified and then the method was applied to the factory experiment and field test for a 39 story building structure installed with a 56 ton AMD. Experimental and field test results showed that the AMD could show the desired control performance and the stable movement within the stroke limit by using the proposed method.
