==Arguments ==

;$LoadCombinationLabel:	Unique LoadCombination Label for reference
;$LoadCombinationDescription  :	Bracketed text. Optional, default: blank {}
;$LoadCombinationModelLabel :	Specifies which LoadCombinationModel is being used. Optional, default: DefaultLoadCombinationModel
: The only LoadCombinationModelLabel available in the currently release is 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


;<$LateralAnalysisArgumentLabel1a $LateralAnalysisArgumentValue1a > <$LateralAnalysisArgumentLabel1b $LateralAnalysisArgumentValue1b> ... 
:Modifiable arguments corresponding to the AnalysisTypeLabel of LateralAnalysisModelLabel1
:Options:
::AnalysisTypeLabel=LoadControl
:::Nstep Tolerance
::AnalysisTypeLabel=DisplacementHistory
:::DisplacementIncrement Tolerance
::AnalysisTypeLabel=TimeHistory
:::DtAnalysis TmaxAnalysis Tolerance DampingRatio


==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.
*The Load and AnalysisModel Arguments specified at the LoadCombination level supersed previously-defined values.
*When LoadType=LateralPushover, $LateralLoadLabel1 $LateralLoadLabel2 ... must all be in the same direction
*Currently, the only LoadCombinationModelLabel DefaultLoadCombinationModel
