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 (refer to http://peer.berkeley.edu).

uniaxialMaterial Concrete01 $matTag $fc $epsco $fcu $epscu

---

$matTag	unique material object integer tag
$fc	concrete compressive strength (with positive value)
$epsco	concrete strain at maximum strength (with positive value)
$fcu	concrete crushing strength (with positive value)
$epscu	concrete strain at crushing strength (with positive value)

Note: For this material class, the sensitivity parameters can be: fc, epsco, fcu, epscu
