SetGeometricNonlinearity {Static Nonlinear}

SetGeometricNonlinearity

Syntax

SapObject.SapModel.LoadCases.StaticNonlinear.SetGeometricNonlinearity

VB6 Procedure

Function SetGeometricNonlinearity(ByVal Name As String, ByVal NLGeomType As Long) As Long

Parameters

Name

The name of an existing static nonlinear load case.

NLGeomType

This is 0, 1 or 2, indicating the geometric nonlinearity option selected for the load case.

0 = None

1 = P-delta

2 = P-delta plus large displacements

Remarks

This function sets the geometric nonlinearity option for the specified load case.

The function returns zero if the option is successfully set; otherwise it returns a nonzero value.

VBA Example

Sub SetCaseStaticNonlinearGeometricNonlinearity()

'dimension variables

Dim SapObject as cOAPI

Dim SapModel As cSapModel

Dim ret As Long

'create Sap2000 object

Set SapObject = CreateObject("CSI.SAP2000.API.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, 2, 144, 2, 288)

'add static nonlinear load case

ret = SapModel.LoadCases.StaticNonlinear.SetCase("LCASE1")

'set geometric nonlinearity option

ret = SapModel.LoadCases.StaticNonlinear.SetGeometricNonlinearity("LCASE1", 2)

'close Sap2000

SapObject.ApplicationExit False

Set SapModel = Nothing

Set SapObject = Nothing

End Sub

Release Notes

Initial release in version 11.02.

Changed nomenclature from Load Cases, Analysis Cases and Response Combinations to Load Patterns, Load Cases and Load Combinations, respectively, in version 12.00.
