Abstract
Numerical modeling of damping effect of an impact damper with granular materials is essential for efficient design of structures set with dampers. In this paper, the method for experimentally evaluating damping effect is proposed. Then the damping effect is modeled as equivalent additional mass, equivalent non-linear spring force and equivalent non-linear viscous damping force. The validity of the methods is examined by comparison with experimental result.
