Friction springs > Stiffness Parameters
Input or modification of the stiffness parameters of Friction Springs. Note that friction springs of this type behave elastically. Hysteretic effects due to Loading-Deloading sequences are not covered.
| Setting | Description |
|---|---|
| From/To/Step | Element series, for which the section properties are input/modified. |
| Element type | Type of the element(s) (see Structure > Elements > Info ) |
| Aero class / EccType | Irrelevant in this context |
| Cx | Translational Spring Element Stiffness in local X-coordinate direction |
| ni-y | Friction coefficient for movement in Y-direction. |
| ni-z | Friction coefficient for movement in Y-direction. |
| CMx; CMy; CMz | Rotational stiffness constants for rotation about x, y, z directions |
