Contents of certification

(1)Hysteresis properties of the visco-elastic damper
This visco-elastic damper, when within the appropriate range of application, possesses consistent hysteresis properties (equivalent stiffness, equivalent damping coefficient, yielded load).
(2)Modeling of hysteresis properties of the visco-elastic damper
When within the appropriate range of application, and given specific conditions for strain (amplitude), temperature, and frequency, the hysteresisproperties of  this visco-elastic damper can be modeled using the Strain Dependency Bilinear Model or the Strain Dependency-type Revised Hardin-Drnevich Model.
(3)Modeling of hysteresis properties of the visco-elastic damper system
Given sufficient stiffness and durability of the mounting framework and surrounding structural framework (columns, beams, braces etc.), this visco-elastic damper  system should have hysteresis properties proportional to the number of visco-elastic dampers installed, and as such can be modeled.
