Abstract A viscoelastic damper is a passive damping control device, which mainly relies on the hysteretic energy dissipation characteristics of viscoelastic material to provide additional stiffness and damping to the structure to reduce the seismic dynamic response of the structure.In the passive control structure design, the storage stiffness of the viscoelastic damper is improved within a certain range, which can effectively reduce the seismic dynamic response of the structure and improve the passive control performance of the viscoelastic damper.This paper presents an experimental study on five types of viscoelastic laminated composite dampers fabricated by adding aramid mesh skeleton material to viscoelastic modified natural rubber.The maximum shear stress, storage shear modulus, loss shear modulus, and equivalent viscous damping ration were measured under different loading schemes to study the regularity of the viscoelastic laminated composite damper properties.The influence of the strain amplitudes, loading frequency, and fatigue to the mechanical properties of these viscoelastic laminated composite dampers were studied.The conclusion is that without changing the matrix of viscoelastic damping material, the storage stiffness of damper can be improved with adding aramid mesh skeleton material in it.Shear strain and fatigue have more effect on the mechanical properties of the viscoelastic laminated composite dampers than loading frequency.

Key words： viscoelastic damper laminated composite mechanical property storage stiffness equivalent viscous damping ratio
