Parameters

Name: Type: System String
The name of an existing or new link property. If this is an existing property, that property is modified; otherwise, a new property is added.

DOF: Type: System Boolean

Fixed

Type:

System Boolean
This is a boolean array, dimensioned to 5, indicating if the specified degree of freedom is fixed (restrained).

Value	Fixity
Fixed(0)	U1 fixity if DOF(0) = True
Fixed(1)	U2 fixity if DOF(1) = True
Fixed(2)	U3 fixity if DOF(2) = True
Fixed(3)	R1 fixity if DOF(3) = True
Fixed(4)	R2 fixity if DOF(4) = True
Fixed(5)	R3 fixity if DOF(5) = True

Nonlinear

Type:

System Boolean
This is a boolean array, dimensioned to 5, indicating if nonlinear properties exist for a specified degree of freedom.

Value	Nonlinear
Nonlinear(0)	U1 has nonlinear properties
Nonlinear(1)	U2 has nonlinear properties
Nonlinear(2)	U3 has nonlinear properties
Nonlinear(3)	R1, not used
Nonlinear(4)	R2, not used
Nonlinear(5)	R3, not used

Note that this item is applicable only for degrees of freedom U1, U2 and U3. For those degrees of freedom, the term Nonlinear(n) applies only when DOF(n) = True and Fixed(n) = False.

Ke: Type: System Double

Ce: Type: System Double

K: Type: System Double

Yield

Type:

System Double
This is an array of yield force terms for the link property. The yield force applies for nonlinear analyses.

Value	Yield
yield(0)	U1, not used
yield(1)	U2 [F]
yield(2)	U3 [F]
yield(3)	R1, not used
yield(4)	R2, not used
yield(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Yield(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

Ratio

Type:

System Double
This is an array of post-yield stiffness ratio terms for the link property. The post-yield stiffness ratio applies for nonlinear analyses. It is the post-yield stiffness divided by the initial stiffness.

Value	Ratio
Ratio(0)	U1, not used
Ratio(1)	U2
Ratio(2)	U3
Ratio(3)	R1, not used
Ratio(4)	R2, not used
Ratio(5)	R3, not used

Note that this item is applicable only for degrees of freedom U2 and U3. For those degrees of freedom, the term Ratio(n) applies only when DOF(n) = True, Fixed(n) = False, and Nonlinear(n) = True.

DJ2: Type: System Double

DJ3: Type: System Double

Notes (Optional): Type: System String

GUID (Optional): Type: System String
The GUID (global unique identifier), if any, assigned to the property. If this item is input as Default, the program assigns a GUID to the property.

Return Value

Returns zero if the property is successfully initialized; otherwise it returns a nonzero value.
