Syntax

SapObject.SapModel.LoadPatterns.AutoSeismic.SetChinese2010

VB6 Procedure

Function SetChinese2010(ByVal Name As String, ByVal DirFlag As Long, ByVal Eccen As Double, ByVal PeriodFlag As Long, ByVal UserT As Double, ByVal UserZ As Boolean, ByVal TopZ As Double, ByVal BottomZ As Double, ByVal JGJ32010AlphaMax As Double, ByVal JGJ32010SI As Long, ByVal JGJ32010DampRatio As Double, ByVal JGJ32010Tg As Double, ByVal JGJ32010PTDF As Double, ByVal EnhancementFactor As Double) As Long

Parameters

Name

The name of an existing Quake-type load pattern.

DirFlag

This is 1, 2 or 3, indicating the seismic load direction.

1 = Global X

2 = Global Y

3 = Global Z

Eccen

The eccentricity ratio that applies to all diaphragms.

PeriodFlag

This is either 2 or 3, indicating the time period option.

2 = Program calculated

3 = User defined

UserT

The user specified time period. This item applies when the PeriodFlag item is 3. [s]

UserZ

This item is True if the top and bottom elevations of the seismic load are user specified. It is False if the elevations are determined by the program.

TopZ

This item applies only when the UserZ item is True. It is the global Z-coordinate at the highest level where auto seismic loads are applied. [L]

BottomZ

This item applies only when the UserZ item is True. It is the global Z-coordinate at the lowest level where auto seismic loads are applied. [L]

JGJ32010AlphaMax

The maximum influence factor.

JGJ32010SI

This is 1, 2, 3, 4, 5 or 6, indicating the seismic intensity.

1 = 6(0.05g)

2 = 7(0.10g)

3 = 7(0.15g)

4 = 8(0.20g)

5 = 8(0.30g)

6 = 9(0.40g)

JGJ32010DampRatio

The damping ratio.

JGJ32010Tg

The characteristic ground period. [s]

JGJ32010PTDF

The period time discount factor.

EnhancementFactor

The enhancement factor.

Remarks

This function assigns auto seismic loading parameters for the Chinese 2010 code.

The function returns zero if the parameters are successfully assigned; otherwise it returns a nonzero value.

VBA Example

Sub AssignSeismicChinese2010()

'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.New3DFrame(BeamSlab, 2, 144, 3, 336, 2, 432)

'add new load pattern

ret = SapModel.LoadPatterns.Add("EQX", LTYPE_QUAKE)

'assign Chinese 2010 parameters

ret = SapModel.LoadPatterns.AutoSeismic.SetChinese2010("EQX", 1, 0.05, 2, 0, False, 0, 0, 0.16, 4, 0.06, 0.4, 1, 1)

'close Sap2000

SapObject.ApplicationExit False

Set SapModel = Nothing

Set SapObject = Nothing
