摘要

With a height of 244.8 m, Beijing Olympic Tower (BOT), situated in the north of Beijing, China, would be a new landmark in Beijing. The BOT is composed of five towers, all of which have large head structures. Preliminary studies demonstrate that the upper part of the tower suffers excessive wind-induced motion which is beyond human comfort limit. In this paper, the effectiveness of Tuned Mass Damper (TMD) on the suppression of wind-induced vibration of the BOT is examined through numerical simulation. Firstly, a finite element model of the BOT is established, and the dynamic characteristics are studied. Secondly, the fluctuating wind pressure is simulated using the data from the wind tunnel test, and time history analysis is carried out to determine acceleration response of the BOT. Lastly, the possible application of a TMD in suppressing wind-induced motions of the tower is investigated, and a TMD is designed to be installed at the top of the BOT. The results clearly show that the designed TMD has a considerable influence on the suppression of the structural response of the tower below human comfort limits.
