Viscous Damper – vsc_dmp

The Viscous Damper (vsc_dmp) curve is a uniaxial response curve modeling the behaviour of a NonLinear Viscous Damper. The Viscous Damper Model consists of a linear spring and a dashpot connected in series and is based on the fractional-derivative Maxwel model described by Makris and Constantinou [1991]. In total four parameters need to be defined for the model:

Initial Stiffness (Kd)
The default value is 200000 KN/m

Damping Constant (Cd)
The default value is 1200 KN/(m/s)0.4

Velocity exponent (α)
The default value is 0.4

Pin Tolerance  (s)
Possible tolerance of the connection of the damper. The default value is 0mm
