Arguments

$MaterialLabel
Unique Material Label for reference
$Fc
Nominal Compressive Strength
$MaterialDescription
Text. Optional, default = blank {}
$rFc
Ratio of actual/maximum compressive strength to nominal cmopressive strength -- confinement effect. Optional, default = 1.0
$fFu
Ratio of residual strength to maximum strength -- confinement effect. Optional, default = 0.2
$E
Elastic Modulus. Optional, default = 57000*$psi*(pow($rFc*$Fc/$psi)
The resultant value will be in the basic Force/Length/Length units.
$epsU
Strain at residual strength. Optional, default = 0.040
$lambda
Ratio between unloading slope at epscu and initial slope. Optional, default = 0.1
$fT
Tensile strength. Optional, default = 0.1*$rFc*$Fc
$Ets
Tension softening stiffness (slope of the linear tension softening branch). Optional, default = $fT/0.002
$WeightDensity
Volumetric Weight Density of Material. Used to calculated section WeightDensity: sectionWeightDensity=$materialWeightDensity*SectionArea. Optional, default = 0.
NOT IMPLEMENTED IN CURRENT VERSION


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. This material is essentially the same as the ConfinedConcrete material, with different default values for maximum-to-nominal and residual-to-nominal strength ratios.
