VB6 Procedure

Function SetEurocode82004_1(ByVal Name As String, ByVal DirFlag As Long, ByVal Eccen As Double, ByVal PeriodFlag As Long, ByVal CT As Double, ByVal UserT As Double, ByVal UserZ As Boolean, ByVal TopZ As Double, ByVal BottomZ As Double, ByVal EURO2004Country As Long, ByVal EURO2004SpectrumType As Long, ByVal EURO2004GroundType As Long, ByVal EURO2004ag As Double, ByVal EURO2004S As Double, ByVal EURO2004Tb As Double, ByVal EURO2004Tc As Double, ByVal EURO2004Td As Double, ByVal EURO2004Beta As Double, ByVal EURO2004q As Double, ByVal EURO2004Lambda As Double) As Long

Parameters

Name

The name of an existing Quake-type load pattern.

DirFlag

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

1 = Global X

2 = Global Y

Eccen

The eccentricity ratio that applies to all diaphragms.

PeriodFlag

This is 1, 2 or 3, indicating the time period option.

1 = Approximate

2 = Program calculated

3 = User defined

CT

The code-specified Ct factor. This item applies when the PeriodFlag item is 1.

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]

EURO2004Country

This is 0, 1, 5, 6, or 10 indicating the country for which the Nationally Determined Parameters (NDPs) are specified.

0 = Other (NDPs are user specified)

1 = CEN Default

5 = Norway

6 = Singapore

10 = Portugal

EURO2004SpectrumType

This is 1 or 2, indicating the spectrum type.

1 = Type 1

2 = Type 2 (Does not apply when EURO2004Country = 6)

EURO2004GroundType

This is 1, 2, 3, 4, 5, or 6, indicating the ground type.

1 = A (Does not apply when EURO2004Country = 6)

2 = B (Does not apply when EURO2004Country = 6)

3 = C

4 = D

5 = E (Does not apply when EURO2004Country = 6)

6 = S1 (Only applies when EURO2004Country = 6)

EURO2004ag

The design ground acceleration in g, ag.

EURO2004S

The soil factor, S. If the EURO2004Country item is not 0, the input value for this item is ignored.

EURO2004Tb

The lower limit of period of the constant spectral acceleration branch, Tb. If the EURO2004Country item is not 0, the input value for this item is ignored.

EURO2004Tc

The upper limit of period of the constant spectral acceleration branch, Tc. If the EURO2004Country item is not 0, the input value for this item is ignored.

EURO2004Td

The period defining the start of the constant displacement range, Td. If the EURO2004Country item is not 0, the input value for this item is ignored.

EURO2004Beta

The lower bound factor, Beta. If the EURO2004Country item is not 0, the input value for this item is ignored.

EURO2004q

The behavior factor, q.

EURO2004Lambda

The correction factor, Lambda.

Remarks

This function assigns auto seismic loading parameters for the Eurocode 8 2004 code.

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

VBA Example

Sub AssignSeismicEurocode82004()

'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 Eurocode 8 2004 parameters

ret = SapModel.LoadPatterns.AutoSeismic.SetEurocode82004_1("EQX", 2, 0.1, 2, 0.075, 0, False, 0, 0, 1, 1, 2, 0.4, 1, 1, 1, 1, 0.2, 2, 1)

'close Sap2000

SapObject.ApplicationExit False

Set SapModel = Nothing

Set SapObject = Nothing
