Abstract

The traditional damper is inconvenient for high-rise structure. The rotor of gimbal gyroscope has two rotational degrees of freedom, and the gyroscope produce moment to resist two orthogonal displacements when the rotor rotates with high speed, so the structure deformation under external force can be reduced. A method for installing some gimbal gyroscopes on the high-rise structure to reduce the structural horizontal and torsional vibration is presented. The movement mechanism of the gimbal gyroscope is introduced, and the dynamic equation for the multi-dimensional control system with gyroscope dampers is established. A steel tower with gyroscope dampers is analyzed to verify the control performance under fluctuating wind loadings and earthquake action. The results show that the dynamic response of high-rise structure can be reduced effectively by the gyroscope dampers with appropriate parameters.
