The Probability-Based Analysis Of TMD Wind-Induced Vibration Control On High-Rise Building

In the field of structural vibration control, the use of dampers in wind-induced vibration control on high-rise building is one of the most important applications, in which, the Tuned Mass Damper (TMD, for short) has been regarded as the simplest while suitable control devices. For its flexibility of installation and significantly effectiveness, it has been widely used in recent years. Based on the studies home and abroad Achievements, research on TMD control on wind-induced vibration of high-rise building are carried out here and summarized as follows:(1) To further verify the good effectiveness of TMD's comfort control on high-rise building, a better method for TMD parameters design is introduced based on Den-Hartog's classic Parameters optimization theory. In this paper, it is set in the King-Key building's wind-induced response control that a kind of pensile TMD is designed and the relationship of target response and TMD parameters is attained.(2) The analysis of effectiveness of TMD control on high-rising building's displacement is carried out. Although TMD is very effective in controlling acceleration of high-rising building caused by wind loads, it has bad effectiveness in displacement, which is the reason for that TMD is mostly used for high-rising building's comfort control.(3) The analysis of TMD control effectiveness on the condition that TMD's parameters Subject to random distribution is carried out. By using the method of Monte Carlo for Stochastic Simulation of each TMD parameters, the conclusion that the deviation of design value of TMD parameter is inevitable, which can lead to disturbance of TMD control effect must be taken care.(4) Appropriate probability distribution models are achieved to described characteristics of probability distribution of target responses.
