GetLoadStrain

Syntax

SapObject.SapModel.LineElm.GetLoadStrain

VB6 Procedure

Function GetLoadStrain(ByVal Name As String, ByRef NumberItems As Long, ByRef LineName() As String, ByRef LoadCase() As String, ByRef DOF() As Long, ByRef Val() As Double, ByRef PatternName() As String, Optional ByVal ItemType As eItemType = Object) As Long

Parameters

Name

The name of an existing line object, line element or group of objects, depending on the value of the ItemTypeElm item.

NumberItems

The total number of strain loads retrieved for the specified line elements.

LineName

This is an array that includes the name of the line element associated with each strain load.

LoadCase

This is an array that includes the name of the load case associated with each strain load.

DOF

This is an array that includes 1, 2, 3, 4, 5 or 6, indicating the degree of freedom associated with each strain load.

1 = Strain11

2 = Strain12

3 = Strain13

4 = Curvature1

5 = Curvature2

6 = Curvature3

Val

This is an array that includes the strain value. [L/L] for DOF = 1, 2 and 3 and [1/L] for DOF = 4, 5 and 6

PatternName

This is an array that includes the joint pattern name, if any, used to specify the strain load.

ItemTypeElm

This is one of the following items in the eItemTypeElm enumeration:

ObjectElm = 0

Element = 1

GroupElm = 2

SelectionElm = 3

If this item is ObjectElm, the load assignments are retrieved for the line elements corresponding to the line object specified by the Name item.

If this item is Element, the load assignments are retrieved for the line element specified by the Name item.

If this item is GroupElm, the load assignments are retrieved for the line elements corresponding to all line objects included in the group specified by the Name item.

If this item is SelectionElm, the load assignments are retrieved for line elements corresponding to all selected line objects, and the Name item is ignored.

Remarks

This function retrieves the strain load assignments to line elements.

The function returns zero if the strain load assignments are successfully retrieved, otherwise it returns a nonzero value.

VBA Example

Sub GetLineElmStrainLoad()
   'dimension variables
      Dim SapObject As Sap2000.SapObject
      Dim SapModel As cSapModel
      Dim ret As Long
      Dim NumberItems As Long
      Dim LineName() As String
      Dim LoadCase() As String
      Dim DOF() As Long
      Dim Val() As Double
      Dim PatternName() As String

   'create Sap2000 object
      Set SapObject = New SAP2000.SapObject

   'start Sap2000 application
      SapObject.ApplicationStart

   'create SapModel object
      Set SapModel = SapObject.SapModel

   'initialize model
      ret = SapModel.InitializeNewModel

   'create model from template
      ret = SapModel.File.New2DFrame(PortalFrame, 3, 124, 3, 200)

   'assign frame object strain load
      ret = SapModel.FrameObj.SetLoadStrain("1", "DEAD", 1, 0.001)

   'create the analysis model
      ret = SapModel.Analyze.CreateAnalysisModel

   'get line element strain load
      ret = SapModel.LineElm.GetLoadStrain("1-1", NumberItems, LineName, LoadCase, DOF, Val, PatternName)

   'close Sap2000
      SapObject.ApplicationExit False
      Set SapModel = Nothing
      Set SapObject = Nothing
End Sub
