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 $LateralLoadArgumentValue2b> ...
- Modifiable arguments corresponding to the LoadType of LateralLoadLabel1
- Options:
- LoadType=LateralPushover
- DMax LateralDirection CycleType NCycles
- LoadType=UniformEQ
- GMdirection GMscale GMfilename
- LoadType=UniformEQ2D
- GMscaleX GMscaleZ GMfilenameX GMfilenameZ
- LoadType=UniformEQ3D
- GMscaleX GMscaleY GMscaleZ GMfilenameX GMfilenameY GMfilenameZ
- LoadType=LateralPushover
- <$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
- AnalysisTypeLabel=LoadControl
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
