Maxwell Dampers > Stiffness Parameters
The Maxwell damper is used for dynamic time history analysis when Non-linear dampers option is selected. The damper has no stiffness in static calculation. The Maxwell element has only one degree of freedom. The direction is defined in Structure > Elements > Length and Angles relative to the global coordinate system. The element consists of a linear spring and a viscous damper arranged in series.
Constitutive law of the element:
F = K*u=sign(v)*C*[abs(v)]^Alpha
- u = displacement
- v = displacement velocity
- F = force in the element
