Abstract: Aiming at the problems of the windinduced vibration of highrise flashing column, the tuned mass damper (TMD) was researched to minimize the vibration, ensure safety operation and prolong service life. By numerical simulation, the top vibration energy decrement rate of the equipment with the TMD and optimal matching parameters of the TMD had been studied. The contours of the energy decrement rate were presented to solve the problem of limited running space of TMD. The results indicate that the TMD is feasible for windinduced vibration control of highrise flashing column, and that the top vibration energy reduces by 47.07% under optimal matching parameters, which has provided valuable preferences for practical application.
