This command is used to construct a concrete material based on the Chinese design code.

uniaxialMaterial ConcreteD $matTag $fc $epsc $ft $epst $Ec $alphac $alphat <$cesp> <$etap>
$matTag integer tag identifying material
$fc concrete compressive strength *
$epsc concrete strain at corresponding to compressive strength*
$ft concrete tensile strength *
$epst concrete strain at corresponding to tensile strength*
$Ec concrete initial Elastic modulus*
$alphac compressive descending parameter*
$alphat tensile descending parameter*
$cesp plastic parameter, recommended values: 0.2~0.3*
$etap plastic parameter, recommended values: 1.0~1.3*

NOTES:

  • Concrete compressive strength and the corresponding strain should be input as

negative values.

  • The value $fc/$epsc and $ft/$epst should be smaller than $Ec.
  • The default value for $cesp and $etap are 0.25 and 1.15, respectively.
