(Note: Newer function available)

Syntax

SapObject.SapModel.LoadPatterns.AutoSeismic.GetEurocode82004

VB6 Procedure

Function GetEurocode82004(ByVal Name As String, ByRef DirFlag As Long, ByRef Eccen As Double, ByRef PeriodFlag As Long, ByRef CT As Double, ByRef UserT As Double, ByRef UserZ As Boolean, ByRef TopZ As Double, ByRef BottomZ As Double, ByRef EURO2004GroundType As Long, ByRef EURO2004SpectrumType As Long, ByRef EURO2004ag As Double, ByRef EURO2004Beta As Double, ByRef EURO2004q As Double, ByRef EURO2004Lambda As Double) As Long

Parameters

Name

The name of an existing Quake-type load pattern with a Eurocode 8 2004 auto seismic load assignment.

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]

EURO2004GroundType

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

1 = A

2 = B

3 = C

4 = D

5 = E

EURO2004SpectrumType

This is 1 or 2, indicating the spectrum type.

1 = Type 1

2 = Type 2

EURO2004ag

The design ground acceleration in g, ag.

EURO2004Beta

The lower bound factor, Beta.

EURO2004q

The behavior factor, q.

EURO2004Lambda

The correction factor, Lambda.

Remarks

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

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