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.
