Study Of Seismic Vibration Control For High-rise Steel Frame Structure With The Combination Of Viscous Dampers And Viscous Damping Walls

With continuous research and development of seismic technology,energydissipation damper device has been used in practical engineering，when an strongearthquake occurs, energy dissipation damper device can create a greater dampingforce and consume a large amount of seismic energy putting into the structure,thusdecrease the dynamic response of the structure and make the structure avoid theoverall structural damage or collapse.At present,although the scholars of all nationshave made a lot of research and reached many great achievement for the dampingperformance of single dampe（rviscous dampers or viscous damping wall）, it is less toset the viscous damping walls and viscous dampers for seismic research in thestrucrure.I this paper,taking12layer steel frame as the research object, A series ofanalysis were done in order to research the damping effect and summarize main rulesof the damping effect using viscous dampers,viscous damping walls and combinationof viscous dampers and viscous damping walls, providing the reference for furtherexperimental Studies in future.This paper describes the deveopment of steel frame and the theory of shockabsorption technology and detailed introduce the structure,classification,influencefactora,the calculation model and damping theory of viscous damper and viscousdamping wall.Under the seismic action,often the local bar in nonlinear state,so thisarticle use Fast Nonlinear Analysis (FNA) method to analyze the damping effect ofhigh-rise steel frame structure using damper(viscous dampers and viscous dampingwalls).Based on the calculation model of high-rise steel frame,in this paper,staticanalysis and modal analysis of the structure is made using finite element softwareSAP2000.According to the structure vibration characteristics,namely the cycle andfrequency of the structure. By inputting the seismic waves, Compare the shockabsorption effect before and after arranging the dampers(viscous dampers and viscousdamping walls) on the structure by using time history analysis method and master thedamping characteristics of the structure by setting viscous dampers or viscousdamping wall.Finally,the reasonable setting maner is selected through comparing theshock absorption effect before and after arranging the combination of viscousdampers and viscous damping walls by using time history analysis method. Accordingto the specification requires, other two seismic waves need to be inputted to comparethe dynamic response of the structure and research the damping effect of the structureusing the combination of viscous dampers and viscous damping walls.The result indicates that when viscous dampers and viscous damping walls are used for vibration control in the high-rise steel frame structure,they can work togetherwell and reduce the dynamic response of the structure.
