Abstract

A variable damping viscous damper is designed, which can change the size of the effective circulation area of the damping fluid under the action of external force to achieve the effect of variable damping coefficient by setting a shaped conical rod member in the damping hole. The mechanical model of the damper was derived and calculated according to the design method by combining the hole shrinkage effect and frictional energy dissipation principle. The damping performance of the dampers was tested by adding them to a six-story reinforced concrete frame structure. The results show that the pore-type variable damping viscous hysteresis damper proposed in this paper has a significant effect of variable damping at larger displacements, and the energy dissipation capacity of the damper increases gradually with the increase of the input frequency; under the action of rare intensity, the dampers have a good damping performance with the top layer displacement and acceleration reduction rate of 24.02% and 14.37% respectively for the reinforced concrete frame model structure in this paper.
