Abstract:
The installation and application of traditional vibration reduction dampers are inconvenient for high-rise structures due to their special shapes and limited interior spaces. The rotor of a gimbal gyroscope has two rotating degrees of freedom, and the gyroscope produceds moments to resist two orthogonal displacements when its rotor rotates with high speed. Hence, the structural deformation of a high-rise building installed with a gimbal grroscope under external loads can be reduced. Here, a method for installing some gimbal gyroscopes on a high-rise structure to reduce its structural horizontal and torsional vibrations was presented. The movement mechanism of a gimbal gyroscope damper was formulated, and the dynamic equation for a multi-dimensional control system with gyroscope dampers was established. A steel TV tower with gyroscope dampers was analyzed to study its vibration control performance under fluctuating wind loadings and earthquake action. The results showed that the dynamic responses of a high-rise structure can be reduced effectively using ginbal gyroscope dampers with appropriate parameters.
