Research Of The Seismic Response Reduction Of Multi-function Vibration-absorption Enclosure Walls Structures

Using the modern control theory to control the high-rise construction structure earthquake respondence is an effective way to reduce the earthquake to the construction destruction at present. As a new type of vibration suppression structure, MVEW(Multi-functional Vibration-absorption to Enclosing Walls) have multi energy dissipation as TMD and damping energy dissipation. In the structure through the clever combination of enclosure walls, TMD and vibration absorption device for reducing earthquake intensity, the advantages of each device are shown, and the characteristic of strong structural adaption and economical efficiency are also obvious.The effect of the Multi-function Vibration-absorption Enclosure Walls Structures which would be used to reduce the earthquake has mainly taken researched by the paper. Firstly the structural arrangement scheme and mechanism are presented, followed by the establishment of the dynamic model, which leads to the motion equation of the system. Then the software SAP2000 was used to establish the analysis models of the MVEW and anti-seismic structure. The works done in this paper mainly include the following several aspects:(1) The earthquake effect and the influence rule of the MVEW were analyzed and summarized in this paper with the building of different floors. And the effect rules of the TMD's mass ratio to the structure was given when with the building of the same floors, conclude the reasonable value of the weight ratio; (2) Regarding the identical structure, through the analysis of the damping ratio, this paper summarized the of the damping ratio, and then confirmed that when mass ratio is a certain, a most superior damping ratio is existed, which can make sure the structure achieves the best ability to absorb of shock effect; (3)The paper analyzed the effect of the frequency ratio to the MVEW, and summarized the influence rule of the frequency ratio. (4) Lastly, the linear time-history seismic analysis for MVEW and anti-seismic structure. The result of the comparison shows that MVEW has an obvious vibration-absorption effect.The research on the MVEW may provide the theory gist and the reasonable scope for parameters during the practical designing works, and it has certain referenced value for constitute of the relative criterions either. Concerning the regional characteristics of Xinjiang as a high occurrence area of earthquake, it is hoped the new type of vibration suppression structure designed in the project will make due contributions to the construction industry in Xinjiang and Western Development.
