BuildingTcl -- addMaterial

Commands

addMaterialData MaterialLabel $MaterialLabel

addMaterialData MaterialModelLabel $MaterialModelLabel

addMaterialData $RequiredArgument1Label $RequiredArgument1Value

addMaterialData $RequiredArgument2Label $RequiredArgument2Value

…

<addMaterialData $InputArgument1Label $InputArgument1Value>

<addMaterialData $InputArgument2Label $InputArgument2Value>

…

addMaterial

Different MaterialModels have different input arguments:

• BuildingTcl -- addMaterial: MaterialModelLabel Elastic
• BuildingTcl -- addMaterial: MaterialmodelLabel Steel
• BuildingTcl -- addMaterial: MaterialmodelLabel ConfinedConcrete
• BuildingTcl -- addMaterial: MaterialmodelLabel UnconfinedConcrete
• BuildingTcl -- addMaterial: MaterialmodelLabel TrilinearHysteretic
• BuildingTcl -- addMaterial: MaterialmodelLabel Steel02

Arguments

$MaterialLabel

Unique Analysis Label for reference

$MaterialModelLabel

Specifies which MaterialModel is being used.

$RequiredArgument1Label $RequiredArgument1Value ...

Labels and corresponding values for MaterialModel-specific required argument.

$InputArgument1Label $InputArgument1Value …

Labels and corresponding values for MaterialModel-specific Input Arguments (Optional)

Notes

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

Example

• Reinforced-Concrete Materials
