GetMultiLinearElastic

Syntax

SapObject.SapModel.PropLink.GetMultiLinearElastic

VB6 Procedure

Function GetMultiLinearElastic(ByVal Name As String, ByRef DOF() As Boolean, ByRef Fixed() As Boolean, ByRef NonLinear() As Boolean, ByRef Ke() As Double, ByRef Ce() As Double, ByRef dj2 As Double, ByRef dj3 As Double, ByRef Notes As String, ByRef GUID As String) As Long

Parameters

Name

The name of an existing multilinear elastic-type link property.

DOF

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

DOF(0) = U1

DOF(1) = U2

DOF(2) = U3

DOF(3) = R1

DOF(4) = R2

DOF(5) = R3

Fixed

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

Fixed(0) = U1 fixity

Fixed(1) = U2 fixity

Fixed(2) = U3 fixity

Fixed(3) = R1 fixity

Fixed(4) = R2 fixity

Fixed(5) = R3 fixity

The term Fixed(n) applies only when DOF(n) = True.

NonLinear

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

NonLinear(0) = U1 has nonlinear properties

NonLinear(1) = U2 has nonlinear properties

NonLinear(2) = U3 has nonlinear properties

NonLinear(3) = R1 has nonlinear properties

NonLinear(4) = R2 has nonlinear properties

NonLinear(5) = R3 has nonlinear properties

The term NonLinear(n) applies only when DOF(n) = True and Fixed(n) = False.

Ke

This is an array of effective stiffness terms for the link property. The effective stiffness applies for linear analyses.

Ke(0) = U1 [F/L]

Ke(1) = U2 [F/L]

Ke(2) = U3 [F/L]

Ke(3) = R1 [FL]

Ke(4) = R2 [FL]

Ke(5) = R3 [FL]

The term Ke(n) applies only when DOF(n) = True and Fixed(n) = False.

Ce

This is an array of effective damping terms for the link property. The effective damping applies for linear analyses.

Ce(0) = U1 [F/L]

Ce(1) = U2 [F/L]

Ce(2) = U3 [F/L]

Ce(3) = R1 [FL]

Ce(4) = R2 [FL]

Ce(5) = R3 [FL]

The term Ce(n) applies pnly when DOF(n) = True and Fixed(n) = False.

dj2

The distance from the J-End of the link to the U2 shear spring. This item applies only when DOF(1) = True. [L]

dj3

The distance from the J-End of the link to the U3 shear spring. This item applies only when DOF(2) = True. [L]

Notes

The notes, if any, assigned to the property.

GUID

The GUID (global unique identifier), if any, assigned to the property.

Remarks

This function retrieves link property data for a multilinear elastic-type link property.

The function returns zero if the property data is successfully retrieved; otherwise it returns a nonzero value.
