GetLoadSurfacePressure

Syntax

SapObject.SapModel.AreaElm.GetLoadSurfacePressure

VB6 Procedure

Function GetLoadSurfacePressure(ByVal Name As String, ByRef NumberItems As Long, ByRef AreaName() As String, ByRef LoadCase() As String, ByRef Face() As Long, ByRef Value() As Double, ByRef PatternName() As String, Optional ByVal ItemTypeElm As eItemTypeElm = Element) As Long

Parameters

Name

The name of an existing area element or group, depending on the value of the ItemType item.

NumberItems

The total number of surface pressure loads retrieved for the specified area elements.

AreaName

This is an array that includes the name of the area element associated with each surface pressure load.

LoadCase

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

Face

This is an array that includes -1, -2 or a nonzero, positive integer, indicating the area element face to which the specified load assignment applies.

-1 = Bottom face

-2 = Top face

>0 = Edge face

Note that edge face n is from area element point n to area element point n + 1. For example, edge face 2 is from area element point 2 to area element point 3.

Value

This is an array that includes the surface pressure load value. [F/L²]

PatternName

This is an array that includes the joint pattern name, if any, used to specify the surface pressure 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 area elements corresponding to the area object specified by the Name item.

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

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

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

Remarks

This function retrieves the surface pressure load assignments to area elements.

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

VBA Example

Sub GetAreaElementSurfacePressureLoad()
   'dimension variables
      Dim SapObject As Sap2000.SapObject
      Dim SapModel As cSapModel
      Dim ret As Long
      Dim NumberItems As Long
      Dim AreaName() As String
      Dim LoadCase() As String
      Dim Face() As Long
      Dim Value() 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.NewWall(2, 48, 2, 48)

   'assign area object surface pressure load
      ret = SapModel.AreaObj.SetLoadSurfacePressure("ALL", "DEAD", -1, .1, , , Group)

   'create analysis model
      ret = SapModel.Analyze.CreateAnalysisModel

   'get area element surface pressure load
      ret = SapModel.AreaElm.GetLoadSurfacePressure("ALL", NumberItems, AreaName, LoadCase, Face, Value, PatternName, GroupElm)

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