addMaterial

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 =

$fFu

Ratio of residual strength to maximum strength -- confinement effect. Optional, default = 0.8

$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.
