【Abstract】 A relatively complete parametric studies of TMD (tuned mass damper) systems in vibration control of single layer latticed saddle shells are presented. Through the random vibration analysis and simulated analysis of time course of single layer latticed saddle shells under the disturbances of horizontal earthquakes, the valuable conclusions are reached with the effects of the mass, the control action distribution and the number of vibration mode control. Besides, the effectiveness of TMD systems is also considered.更多还原
