Abstract

With the increasing height of buildings, the frame-central core tube-outrigger structure system is widely used in super-tall buildings. At the same time, it becomes more and more popular to employ multi-outriggers in taller and super high-rise buildings. However, because of the fact that the vibration period of these skyscrapers is close to that of the fluctuating wind, the acceleration of structure caused by wind generally exceeds the level of comfort regulated by the corresponding codes. Targeting on a super high-rise building with multi-outriggers, viscous dampers are installed between an outrigger at some height and the mega column, namely to adopt energy dissipation outrigger with viscous dampers, thus the overlarge wind-induced accelerations will be under control. Besides, the article will also focus on the effectiveness of the wind vibration control by viscous dampers installed in an outrigger at different levels.
