SetPDeltaForce

Syntax

SapObject.SapModel.FrameObj.SetPDeltaForce

VB6 Procedure

Function SetPDeltaForce(ByVal Name As String, ByVal PDeltaForce As Double, ByVal Dir As Long, ByVal Replace As Boolean, Optional ByVal CSys As String = "Global", Optional ByVal ItemType As eItemType = Object) As Long

Parameters

Name

The name of an existing frame object or group, depending on the value of the ItemType item.

PDeltaForce

The P-Delta force assigned to the frame object. [F]

Dir

This is 0, 1, 2 or 3, indicating the direction of the P-Delta force assignment.

0 = Frame object local 1-axis direction

1 = Projected X direction in CSys coordinate system

2 = Projected Y direction in CSys coordinate system

3 = Projected Z direction in CSys coordinate system

Replace

If this item is True, all existing P-Delta force assignments to the frame object are removed before assigning the specified P-Delta force. If it is False, the specified P-Delta force is added to any existing P-Delta forces already assigned to the frame object.

CSys

This is the name of the coordinate system in which the projected X, Y or Z direction P-Delta forces are defined. This item does not apply if the Dir item is zero (frame object local 1-axis direction).

ItemType

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

Object = 0

Group = 1

SelectedObjects = 2

If this item is Object, the assignment is made to the frame object specified by the Name item.

If this item is Group, the assignment is made to all frame objects in the group specified by the Name item.

If this item is SelectedObjects, assignment is made to all selected frame objects, and the Name item is ignored.

Remarks

This function assigns P-Delta forces to straight frame objects. P-Delta force assignments do not apply to curved frames.

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

VBA Example

Sub AssignFramePDeltaForce()
   'dimension variables
      Dim SapObject As Sap2000.SapObject
      Dim SapModel As cSapModel
      Dim ret As Long

   '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 P-Delta force
      ret = SapModel.FrameObj.SetPDeltaForce("ALL", 100, 0, True, , Group)

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