Specifies the following values:

TYPE = X Y Z GUI LIM

MU - Specifies the static friction coefficient. Friction provides resistance to movement along the direction normal to the restraint line of action. The magnitude of the friction force is equal to MU * Fn, where Fn is the normal force on the restraint. You can automatically assign a friction coefficient to every new translational restraint by assigning a value to the Coefficient of Friction box in the configuration. For more information, see Coefficient of Friction (Mu).

TYPE = XROD YROD ZROD

Typical units (depending on your unit system):

  • lb

  • N

Fi - Specifies the initial spring load. Leave this box blank for a rigid YROD. If you use YROD to model a spring hanger, type the hanger stiffness into the STIF box. Type the initial cold load on the hanger.

TYPE = X2 Y2 Z2 RX2 RY2 RZ2

Typical units (depending on your unit system):

  • lb

  • N

Fy - Specifies the yield load. If the load on the support is less than Fy then the initial stiffness K1 is used. If the load on the support is greater than Fy then the second stiffness K2 is used.

TYPE = XSPR YSPR ZSPR

Typical units (depending on your unit system):

  • lb

  • N

F - Specifies the initial spring cold load. This input is required and is almost always positive.

TYPE = XSNB YSNB ZSNB

na - Not Applicable. This box is not used when the restraint TYPE is snubber.
