Arguments

$AnalysisModelLabel

Unique Analysis Label for reference

$AnalysisModelDescription

Text. Optional, default = blank {}

$DtAnalysis

Time step for analysis, in basic time units. Optional, default = 0.01

$TmaxAnalysis

Maximum analysis duration, in basic time units. Optional, default = 50.0

$DampingRatio

Percent-of-critical damping ratio. Optional, default = 0.002

$DampingModelLabel

Damping model to be used in Time-History analysis. Optional, default = StiffnessProportionalDampingModel

The current version does not allow the user to modify the parameters of the damping model.

Options

MassProportionalDampingModel

StiffnessProportionalDampingModel, (same as InitialStiffnessProportionalDampingModel )

MassAndStiffnessProportionalDampingModel

InitialStiffnessProportionalDampingModel -- Stiffness-Only proportional damping

CurrentStiffnessProportionalDampingModel -- Stiffness-Only proportional damping

CommittedStiffnessProportionalDampingModel -- Stiffness-Only proportional damping

$Tolerance

Tolerance value for convergence test. Optional, default = 1e-8

$constraintsType

OpenSees constraints Command. Optional, default = Transformation

$alphaSP

alpha value for Single-Point Constraints when using the OpenSees Penalty Method . Optional, default = 1e6

$alphaMP

alpha value for Multi-Point Constraints when using the OpenSees Penalty Method . Optional, default = 1e6

$numbererType

OpenSees numberer Command. Optional, default = RCM

$systemType

OpenSees system Command. Optional, default = BandGeneral

$testType

OpenSees test Command. Optional, default = EnergyIncr

$maxNumIter

Maximum number of iterations when peforming the OpenSees test Command. Optional, default = 6

$printFlag

Print flag when peforming the OpenSees test Command. Optional, default = 0

$NstepReduceIncrement

Number of steps to reduce original $DisplacementIncrement when the convergence test first fails. Optional, default = 4

$maxNumIterConverge

Maximum number of iterations when performing the OpenSees test Command after the $DisplacementIncrement has been reduced by $NstepReduceIncrement . Optional, default = 2000

$printFlagConverge

Print flag when peforming the OpenSees test Command after the $DisplacementIncrement has been reduced by $NstepReduceIncrement . Optional, default = 0

$algorithmType

OpenSees algorithm Command. Optional, default = Newton

$NewtonLineSearchRatio

Factor used by the Newton Algorithm with Line-search in OpenSees algorithm Command. Optional, default = 0.8

$algorithmCount

OpenSees algorithm Command. Optional, default = 5

$integratorType

OpenSees integrator Command. Optional, default = Newmark

$NewmarkGamma

Gamma factor when Newmark OpenSees integrator Command is used. Optional, default = 0.5

$NewmarkBeta

Beta factor when Newmark OpenSees integrator Command is used. Optional, default = 0.25

Notes

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