Research On Design Method Of Shear Wall Structure Coupling Viscoelastic Damper

In recent years,with the acceleration of the pace of urbanization in China,more and more people have settled in cities,which has led to a shortage of urban land resources.In order to solve this problem,the development of high-rise buildings has become an effective measure.The high-rise shear wall structure is a common and main structural form of high-rise buildings.At the same time,the application of energy dissipation technology in recent years is also very extensive,and the practical effect is also ideal.In addition,the experimental research and theoretical calculation of the vibrating structure of the viscoelastic damper have gradually matured.In order to promote its application in engineering,practical computational analysis methods need to be solved urgently.At present,most scholars have carried out related research on the coupling beam metal damper,but there are fe w researches on the coupling beam viscoelastic damper.In this paper,a practical study on the practical design method of the shock-absorbing structure of the beam-bonded viscoelastic damper in the shear wall structure is carried out in combination with en gineering examples.Firstly,this paper introduced the stress characteristics of the coupling beam and the coupling beam damper in the shear wall structure.It also introduced several design analysis methods in the damping structure,the principle method of seismic wave,the development history and use function of SAP2000 finite element software.In addition,it derived the stiffness formula of the connecting beam at the beam damper.It analyzed the relationship between the stiffness of the metal damper an d the stiffness of the connecting beam in detail.It is concluded that it should be controlled to 30%-50% of the stiffness of the connecting beam.It also analyzed the two simulation methods of the coupling beam in the shear wall structure with the couplin g beam damper and the damping effect of the damper in the upper,middle and lower parts of the structure.Secondly,this paper introduced the basic principle and basic structure of the viscoelastic damper,the basic properties of the viscoelastic material,the restoring force model of the viscoelastic damper.In addition,the two parameter desigmethods of the viscoelastic damper and the relationship between the stiffness of the viscoelastic damper and the stiffness of the connecting beam are introduced in detail.It is concluded that the damper stiffness should be in the range of 10%-30% of the stiffness of the connecting beam.The actual design flow of the shock absorbing structure of the viscoelastic damper is summarized based on the damping design process of energy dissipating component.Finally,this paper carried out an analysis of a high-rise shear wall structure in actual engineering.It analyzed and compared the shock-absorbing structures with viscoelastic dampers and metal dampers.In addition,it also carried out a simple economic analysis of the traditional seismic structure,the shock absorbing structure with viscoelastic dampers and metal dampers.
