The Control Effect Analysis of the Variable Frequency TMD Applied to the Frame Structure

Frequency variable TMD system is developed based on the conventional TMD system, which has multiple frequencies and thus merits of MTMD. Frequency variable TMD can effectively reduce the dynamic response of structure induced by its own frequencies. In this study, this technique is applied to dynamic analysis of high-rise building. The results show that frequency variable TMD system can optimize the dynamic response of the structure and control the vibration effectively, compared to conventional TMD system.
