| Abstract |
Increasing height of tall buildings often requires supplementary damping system such as tuned mass damper (TMD) for occupant comfort in wind condition. Since the guide rail type TMD has advantages of smaller space requirement and bidirectional controllability, it is often preferred in Korea to the pendulum type TMD. For the guide rail type TMD, it is important to reduce the friction force between a moving mass and guide rails. In this paper, laminated rubber bearing is used to reduce the friction force in the guide rail type TMD. This rubber bearing also provide an additional stiffness and thereby the number of required spring can be reduced significantly. The performance of TMD is tested in factory as well as in site. It was found that the use of laminated rubber bearing reduced the friction force dramatically while the control performance target was met. |
