Friction Pendulum TMD and its Control Effectiveness for Wind-Induced Vibration

Abstract:

A new type of frictional pendulum TMD is designed. The wind-induced vibration of Henan Art Center Symbolic Tower with and without TMD is analyzed. The structural design of frictional pendulum TMD is presented in detail. The equivalent analysis model is established. The 3D analysis of the symbolic tower is established using SAP2000. The non-linear LINK unit in SAP2000 is used to simulate frictional pendulum TMD. Then, the non-linear analysis of wind control effectiveness of frictional pendulum TMD is carried out. The analysis results demonstrate that optimal frictional force can be chosen according to design wind loads and the control effectiveness can be over 30% with the chosen frictional force under 0.3 to 2 times of the designed wind loads.
