Arguments

$LoadCombinationLabel

Unique LoadCombination Label for reference

$LoadCombinationDescription

Bracketed text. Optional, default: blank {}

$LoadCombinationModelLabel

Specifies which LoadCombinationModel is being used. Currently, Optional, default: DefaultLoadCombinationModel

$GravityLoadLabel1 ...

Previously-defined Gravity Load Label, specified within the model.

At leaset one GravityLoadLabel must be specified in each LoadCombination.

$LoadFactorGravity1 ...

Scaling factor for GravityLoadLabel1. Optional, default=1.0

$InertialMassFactorGravity1 ...

Inertial-Mass factor for GravityLoadLabel1. Optional, default=1.0

$GravityAnalysisModelLabel

Previously-defined AnalysisModelLabel, used in performing load-controlled gravity analysis : Optional, default= DefaultLoadControl

$NstepGravity

Number of step to be taken in gravity-load analysis. This value supersedes what has been specified in the analysis model $GravityAnalysisModelLabel

$ToleranceGravity

Convergence-test tolerance used in gravity-load analysis. This value supersedes what has been specified in the analysis model $GravityAnalysisModelLabel

$LateralLoadLabel1 ...

Previously-defined Lateral Load Label, specified within the model.

$LateralAnalysisModelLabel1

Previously-defined AnalysisModelLabel; Only AnalysisModelLabels of the type consistent with the LoadType of $LateralLoadLabel1 can be used.

$LoadFactorLateral1...

Scaling factor for LateralLoadLabel1. Optional, default=1.0

<$LateralLoadArgumentLabel2a $LateralLoadArgumentValue2a> <$LateralLoadArgumentLabel2b $LateralLoadArgumentValue2b> ... >

Modifiable arguments corresponding to the LoadType of LateralLoadLabel1

Options:

LoadType=LateralPushover

DMax LateralDirection CycleType NCycles

LoadType=UniformEQ

GMdirection GMscale GMfilename

LoadType=UniformEQ2D

GMscaleX GMscaleZ GMfilenameX GMfilenameZ

LoadType=UniformEQ3D

GMscaleX GMscaleY GMscaleZ GMfilenameX GMfilenameY GMfilenameZ AnalysisModelLabel

Notes

The addLoadCombination command must be placed at the end of each LoadCombination-data definition, as it takes all data defined since the last addLoadCombination command and define the LoadCombination.
