This command is used to construct a uniaxial Kent-Scott-Park concrete material object with degraded linear unloading/reloading stiffness according to the work of Karsan-Jirsa and no tensile strength. (REF: Fedeas).
uniaxialMaterial Concrete01 $matTag $fpc $epsc0 $fpcu $epsU
$matTag |
unique material object integer tag |
$fpc |
concrete compressive strength at 28 days (compression is negative)* |
$epsc0 |
concrete strain at maximum strength* |
$fpcu |
concrete crushing strength * |
$epsU |
concrete strain at crushing strength* |
*NOTE: Compressive concrete parameters should be input as negative values.
The initial slope for this model is (2*$fpc/$epsc0)
